A WINTER STORM WARNING IS IN EFFECT FOR FOR MONDAY NIGHT AND TUESDAY MORNING… ANOTHER ARCTIC BLAST IS EXPECTED LATER IN THE WEEK

As it looks right now (8:00 AM Monday, Feb 16), significant snow accumulations seem likely for Southeastern Virginia and portions of Northeastern North Carolina. A low pressure system developing near the Gulf Coast will spread snow into our region beginning late Monday afternoon or evening. The snow is expected to pick up in intensity during the night, possibly becoming heavy at times. The snow may mix with sleet and/or freezing rain in some areas closest to the coast. Although this could hold accumulations down a bit in some areas, the very latest update out of the National Weather Service office in Wakefield suggests that the models are trending just a bit further south with the rain/snow line. Accumulations will most likely range from 1-3 inches in far southeastern Virginia Beach to 4-6 inches on the peninsula. Snowfall totals are highly dependent on how much (if any) sleet or freezing rain mixes in. If it stays all snow during the periods of heaviest precipitation overnight, snow amounts could be higher. Since it has been so cold of late, the snow will stick immediately and accumulate, even on the roadways. The precipitation will end Tuesday morning but temperatures are not expected to warm up that much Tuesday afternoon. Another Arctic blast is expected to arrive later Wednesday. Thursday and Friday are expected to be brutally cold. Then, we may have to deal with another low pressure system over the weekend. Stay safe out there and thanks for reading.

THERE IS AN INCREASED POSSIBILITY OF A WINTER STORM AFFECTING SOUTHEASTERN VIRGINIA MONDAY NIGHT INTO TUESDAY

This is just a brief update to let you all know that some of the computer models are now indicating that a winter storm may impact Southeastern Virginia beginning Monday night and ending during the day on Tuesday or possibly during the evening hours. In my previous post, I mentioned the possibility of snow, but it seems that the onset of precipitation will be much sooner than was initially expected. There is quite a bit of uncertainty regarding this system (both the timing and precipitation type), so I think it is still too soon to provide projected snowfall amounts. Since a changeover to sleet, freezing rain, or rain is possible in some parts of the area, it is going to be very difficult to nail down potential snowfall accumulations. (Please read my Weather Fact entitled “Predicting Snow in the Hampton Roads Area… Why is it so challenging?”). Meanwhile, we will continue to see the strong winds today (Sunday) and very low wind chill readings, but the winds will slowly subside as the deep low pressure area that has brought the blizzard to Eastern New England moves away. Please monitor updates from the local media and the National Weather Service. I will have an update Monday morning.

AN ARCTIC COLD FRONT WILL CROSS THE HAMPTON ROADS REGION SATURDAY NIGHT… HIGH WINDS AND VERY COLD TEMPERATURES WILL MAKE SUNDAY MISERABLE FOR ANYONE GOING OUTDOORS… A LOW PRESSURE SYSTEM THAT IS EXPECTED TO DEVELOP NEAR THE GULF COAST MAY BRING SNOW TO PARTS OF VIRGINIA ON TUESDAY AND WEDNESDAY

If you need to do anything outdoors this weekend, I recommend doing it on Saturday. As the headline states, an Arctic cold front will be sweeping through Southeastern Virginia Saturday night ushering in a blast of cold air. There may be some rain and snow showers Saturday evening bringing possibly a coating of snow to mostly grassy surfaces. It is expected to be similar to what we saw last Thursday evening. It will be a quick mover so significant snow accumulations aren’t likely. On Sunday, temperatures are expected to remain in the twenties and winds will be very strong and gusty. Low temperatures on Monday morning are expected to be in the low to mid-teens. The current upper-level wind configuration across North America is causing these brutally cold air masses to plunge into the Eastern U.S. What about the chances of snow? Up until now, every time a low pressure system approached our region this winter season, temperatures have risen above freezing resulting in rain. Most times when a low pressure system passes to our north or west, we get mainly rain. When the storm track brings low pressure systems to our south and east, snow is possible in certain situations. Recent changes in the pattern over the past few days make the next storm system a lot more interesting. A low pressure system is expected to take shape near the Gulf Coast on Monday. This system is expected to track northeast on a track that should take it along the North Carolina Coast. That type of track could bring significant snow to parts of Virginia so stay tuned. There is some disagreement in the current computer models regard the track of this storm and how much cold air will be around on Tuesday and Wednesday. If the low pressure system is able to bring in milder air from off the ocean, then we will see mostly rain here in Hampton Roads. Even so, some snow could fall either at the precipitation’s onset or when the low pressure system is pulling away to our north and east…. Speaking of snow, Eastern New England, which has been hit hard this winter, is expecting yet another major snowstorm this weekend as a storm system intensifies rapidly off the coast. High winds will be a major issue for them which could result in power outages up there. This is the same system that will bring the strong winds to our region on Saturday night and Sunday. I’m going to try to post an update on Monday. That’s it for now. Have a great weekend!

VERY COLD TEMPERATURES ARE LIKELY ON FRIDAY AND AGAIN LATER IN THE WEEKEND

There are going to be several very chilly air masses plunging into the eastern U.S. over the next week or so. What does this mean for us here in Hampton Roads? A strong cold front is going to move through our region Thursday afternoon. As it looks right now, behind the front, temperatures will plunge from around 50 degrees to the low 20’s by Friday morning! Gusty winds will make it feel even colder. It is possible that we may see a few snow flurries/showers but significant accumulations are not expected at this time. Then, we should have a brief warm up on Saturday (Valentine’s Day) as the next cold front approaches. On Sunday, temperatures are expected to possibly be even colder than Friday’s temperatures! For those of you who don’t like the cold weather, the good news is that the average temperature has begun to climb and will continue to do so until later July. That’s it for now. Thanks for reading and have a great day!

HAMPTON ROADS GETS A BREAK FROM THE COLD WEATHER… THE TIMING COULDN’T BE BETTER SINCE IT’S THE WEEKEND… DON’T GET TOO USED TO THE MILD WEATHER AS ANOTHER ARCTIC BLAST MAY IMPACT OUR REGION LATER IN THE WEEK

Temperatures this Saturday afternoon are quite pleasant for this time of year. High pressure to our south is causing a southwesterly breeze, which is bringing in some of that milder air that folks across parts of the south and southwest have been enjoying. We’ll see similar conditions on Sunday and it will probably be even warmer. Over the next few days, there is expected to be a front that will run generally west to east well to our north. The front will separate very chilly air to the north from relatively milder air to the south. Areas of low pressure are expected to ride along the front creating precipitation to our north. Some light rain is possible on Monday. If you are traveling to the Northeastern States, significant snow is likely in some areas that were already hard hit this winter. After the possibility of light rain or showers on Monday, the remainder of the week is expected to be dry for the most part. There is expected to be another Arctic blast later in the week, probably Thursday night and Friday. Stay tuned as the timing of the Arctic front is uncertain right now. According to the National Weather Service, we may not even get above the freezing point on Friday with very windy conditions! Ouch! We’ll see if that forecast verifies as it is several days from now. So, enjoy the above normal temperatures this weekend and get outdoors if you can. That is it for now. Have a great weekend!
