Update 12:30 AM Thursday EDT (11:30 AM Thursday in Phuket) The 00Z GFS continues with basically the same story, with one new wrinkle. It shows an extra batch of precipitation on the west side of the storm as the center passes near the coast. IF that happens (and with the available moisture and the system deepening, it is plausible), there
Thursday 10AM (Phuket, Thailand) Wednesday 11PM EDT Storm number one that I discussed in my last post is now causing snow in much of Pennsylvania, except for the extreme southeast. The second storm seems to be following the previous GFS idea, and suggests heavy snow from Thursday night into Friday from the mountains of West Virginia across central or east-central
Tuesday 9:38 a.m. (Thailand Time) (11 hours earlier, EDT) My wife and I are spending this week with our son and daughter-in-law who live in Taiwan. We are being treated to vacation in Phuket, Thailand. It is a beautiful place and the people we have met are very friendly. This morning, it is pouring. The winds are creating white caps
Wednesday 8 a.m. Note: I will be out of the office until April 5. A storm that has caused everything from heavy snow to tornadoes is moving into the East today. This pressure analysis shows where the storm was centered at 9 a.m. The winds are strong out of the southwest to the south of the low pressure area, and
Tuesday 8 a.m. Yesterday's storm is gone, but another one is on the way. This one that caused heavy precipitation on the West Coast will cause severe thunderstorms in Missouri, Illinois and Iowa today, then from the Ohio Valley to North Carolina and Tennessee tomorrow. Ahead of the storm, chilly air will seep southward from eastern Canada. Snow will fall
Monday 7:55 a.m. When we reach 30, 40, 50, 60, 70, etc., years old, it seems like quite a jump in our personal age perceptions. However, we soon realize that most changes are gradual. And so it is that just because it is now spring this does not mean it will become warmer right away. The morning weather map showed
Friday 8AM May can sometimes feel like March for a while if you may, and sometimes March feels like May, if you will. Today will bring a taste of May if you will, but the May-style weather will quickly march, and there are no maybes about it, if you will. In other words, with a taste of May on this
Thursday 7:50 AM Top o' the mornin to you. Let's hope the Luck of the Irish is with you today, and that some of it helps the less fortunate. St. Patrick's Days of the past have been momentous. In 1776, the British abandoned Boston on this date. A snowstorm on March 5th had thwarted their plans to attack the American
Wednesday 8 a.m. The storm that caused rain in the Middle Atlantic states last night also brought some wet snow to the higher elevations from central Pennsylvania into upstate New York. When I woke up at 2:30 to get ready for work, there was a covering of slush in the back yard. My house is at an altitude of 1,400
Tuesday 7:45 a.m. A low pressure area that was centered near Louisville, Ky., early this morning will move northeastward and eventually merge with another low pressure area that is advancing eastward from Manitoba. Rain is moving northeastward from the Ohio and Tennessee valleys. Rain should arrive in the D.C. area before nightfall, advance into New York City after midnight then
Monday 7:30 a.m. In today's video, I show the projected upper air flow for later this week and early next week. If it is right, much milder air is on the way for most of the Great Lakes and Northeast. Meanwhile, a low pressure area from the southern Plains is moving northeastward. It will send rain up the Ohio River
Friday 5:10 AM Here is an early video. Rain changed to snow as expected from the lower Great Lakes to the Ohio Valley. The main rain area leaves the New York City area and proceeds through New England. The Washington to New York City corridor will have a dry weekend.
Thursday 8 a.m. Early this morning, there was a low pressure area centered near Detroit and another over extreme southern West Virginia... both connected by a cold front that was advancing slowly eastward. The main corridor of rain that was firmly entrenched in the Washington, D.C., area, had just arrived in Philadelphia but still had not reached New York City.
Wednesday 8 a.m. A storm moving northeastward from Illinois is causing snow across the upper Great Lakes as well and will cause snow for a while over the higher terrain from western Virginia through central Pennsylvania... before changing to heavy rain. This map showed the pressure pattern at 7 a.m. EST. While it becomes milder along the coast and also
Tuesday 7:20 a.m. EST Today's video shows the likely progression of the next storm as it heads from the Southwest states toward the Great Lakes and Northeast. It includes discussion of the uncertainty surrounding the nature of the storm once it gets to the East Coast. If it stays as one basic unit, flooding rain would affect the Middle Atlantic
Monday 7 a.m. Early this morning, a strong low pressure area was moving northeastward through New England. The little pressure analysis map shows where it was located at 5 a.m. While it was mild and rainy in the I-95 corridor, heavy snow fell from the mountains of West Virginia through the middle of Pennsylvania and on into central New York
Friday 7:10 AM In today's video, we look at some precipitation moving northeast from the Ohio Valley and eastern Great Lakes. The weekend will be milder in the I95 corridor with the bulk of the expected rain falling in the Washington-to-Philadelphia area on Sunday and from New York City to Boston later Sunday or Sunday night into early Monday. I
Thursday 7AM Bitterly cold air blasted into New England last night on the strength of face-freezing winds from the remote frozen hinterlands of the Arctic. Speaking of the Arctic, you may have seen the story about how this winter has been less cold than average in the Arctic, and how global warming may be responsible for the extreme snow events
Wednesday 8 a.m. After a brief warmup for the I-95 corridor today, a strong shot of cold air will charge in tonight. Despite sunshine, temperatures will hold in the teens in northern New England and top out only in the 30s in most of Maryland. At first, gusty winds will sharpen the effect of the chill, but as the high
Tuesday 7:25 a.m. The video starts with a picture of the critter I associate with the many changes we see in March: the chameleon. Much of the nation is dry today. Across the Great Lakes and Northeast, temperatures will be moderate today. Tomorrow will be temporarily milder in the Northeast while it gets colder in the Great Lakes. That chill
Monday 7:25 a.m. Here is today's video. If you live anywhere between the Ohio and Tennessee valleys and the Middle Atlantic coast, stay alert for any severe weather warnings for your location today. The cold responsible for triggering the rain and thunderstorms will be offshore by late tonight, and a chilly but bright day will follow for most of the
Friday 7:30 AM please SEE NOON UPDATE BELOW The storm center responsible for a wide range of inclement weather today has been very easy to track with a map analysis program we use in the office. Here are the maps from 2AM and 6AM EST this morning. At 2AM, there were centers in northern and eastern Kentucky, but four hours
Thursday 10 a.m. The storm coming out of the Plains has just about everything: 1. A severe weather outbreak focused in and around Arkansas and Tennessee. 2. Significant snowfall from Kansas City through Chicago and Peoria through Detroit and Cleveland to Buffalo and over northern New England. Places like Cleveland, Buffalo and Montpelier (Vermont) should get 6-12 inches. 3. Substantial
Wednesday 8:20 a.m. As a giant high pressure area moves south from Canada's Northwest Territories, bitterly cold air will pour into the northern Rockies, and some of it will spill across the mountains to chill the cities of the Pacific Northwest. Snow will settle on Seattle. Usually, when it gets cold in the West, there is warming in the East.
Tuesday 7 a.m. The headline theme is pretty obvious. Since storms develop along the boundaries between cold and warm air masses, the track each storm takes is a big deal. For example, last night, a low pressure area moved through Virginia. South of the storm, at Raleigh, N.C., the temperature was still 64 degrees at midnight. North of the storm,
Monday 8:25 a.m. The headline may seem ominous, but March is little more than a week away. In the meantime, there is a front extending from a low pressure area over southern Illinois to an other low pressure area over eastern Maryland. The easternmost storm dumped 8-12 inches of snow from extreme southwestern New York across much of northern Pennsylvania.
Thursday 7:05 AM The long-advertised warm-up is proceeding nicely. Early morning temperatures included 54 at Des Moines, Iowa (where the s in Des is silent), 50 degrees at Des Plaines, Illinois (where the s in Des is audible), 48 in Pittsburgh, Pennsylvania (where the city name ends in h), and 60 in Pittsburg, Kansas (where it doesn't end in h).
Wednesday 6:20 a.m. The high pressure area that marks the center of the cold air mass that chilled the Northeast yesterday is now offshore. The clockwise flow around it will now create a southwesterly flow of milder air. Since the next cold front is way out in the Dakotas, the warmup will last through Friday. The cold will move though
Monday 7 a.m. Happy Valentine's Day! It's Valentine's Day with thoughts of Cupid I hope the forecast doesn't turn out stupid All winter long, warmth was dismissed It was so cold and snowy many people got really tired of it The morning map shows high and lows Moving along with the upper air flows But until a southern low comes
Friday 6:35 a.m. Basic forecast outline for the Northeast: 1. Less cold this weekend than recently. 2. A chilly shot from the northwest later Monday in Tuesday. 3 .A major warmup later next week... approaching 50 in Massachusetts and 60 degrees in Maryland. 4. Cold air returns early the following week, but its staying power is questionable. Here's today's video:
Thursday 6:25 AM A storm that dumped more than a foot of snow on parts of Arkansas and sent temperatures to the teens in Dallas and the 20s in Houston is now off the East Coast and moving away. Light snow made it as far north as Washington, Baltimore and Philadelphia overnight, but in all three cities sunshine will dominate
Wednesday 6:45 a.m. Today is the anniversary of the coldest winter morning ever for many cities in the Northeast: February 9, 1934. The -18 reading at Boston, -15 in New York City, -11 at Philadelphia and -21 in Buffalo were all records for the coldest morning ever in recorded history. Coming back to the present day, on top of Mount
Tuesday 7:45 a.m. A bitterly cold air mass is spreading across the Great Lakes and into the Northeast today and tonight, so keeping warm will be the number one challenge for the next few days. Maybe I shouldn't have said that. In some areas, there is so much snow and ice that there seems to be nowhere to put it.
Monday 8 a.m. At 7 a.m. yesterday, the temperature at Bismarck, N.D., was 26 degrees. This was 58 degrees higher than it was on the morning of Groundhog Day. This morning, it is down to 3 degrees.

Friday 7:40 AM The next few days will not be as cold as some recent days in the Midwest and Northeast, but very cold air will return to the Great Lakes in the Monday-to-Tuesday period, and then push into the Northeast. The most bitter weather will be in the Midwest, where places like Chicago may have temperatures in the single
Thursday 8:20 AM Here is the video. I will have more later, including some pictures from my visit to Punxsutawney. This is just as they are getting ready to pick up Phil the groundhog. Here, I am with Bill Deely, president of the Groundhog Club Inner Circle. I was honored to be inducted into the National Meteorologist Hall of Fame
Tuesday 7:30 a.m. A mammoth storm is causing just about every kind of weather we get to see during the year. This morning, it was pulling warm air north from the Gulf of Mexico. It was 61 degrees in New Orleans at daybreak. At the same time, screaming gales with gusts past 45 miles per hour were blowing snow-filled air
Monday 7:59 a.m. A storm now organizing over the southern Rockies will bring its heaviest snow to Kansas City tomorrow, Chicago tomorrow night and central and northern New England on Wednesday. However, lighter snow may precede the main event from the Great Lakes to Northeast by a whole day. Today, we see a stationary front extending from South Carolina to
Friday 7:20 AM In the video, I discuss the weak low pressure areas that can bring light snow amounts from the Great Lakes to the Northeast, then we speculate about a storm that could move in on Groundhog Day (next Wednesday).
Thursday 8:20 a.m. So far this winter, New York City has had close to 55 inches of snow. In all of last winter, the total was half a foot less. By this time last winter, the city had only received a little more than 13 inches. In Philadelphia, the accumulation has already reached about 37 inches, which is very close
Wednesday 7:15 a.m. Here is the 7 a.m. video. More later. 9 a.m. Notes Part one of a two-part snowstorm moved into the Middle Atlantic states. The snow fell so heavily in the Philadelphia area that the morning commute turned into a nightmare, with multi-mile backups and hundreds of accidents. Meanwhile, the early snow in Washington and Baltimore turned to
Tuesday 7:25 a.m. In today's video, we step through the GFS model maps to get an idea about what a storm from the Gulf of Mexico will do. There is still variation in the model collection. The 1 a.m. version of NMM-WRF model was farther east with the storm, and thus predicted less precipitation. Last night's ECMWF trended farther west
The National Weather Service in State College has issued an urban and small stream flood advisory for counties in Northcentral Pennsylvania. Doppler radar indicated heavy rain was falling from multiple lines of intense and slow moving showers. more»
