THE UPPER-LEVEL WIND PATTERN REMAINS BASICALLY UNCHANGED… ARCTIC AIR MASSES CONTINUE TO PLUNGE INTO THE UNITED STATES… A SYSTEM WILL HAVE TO BE WATCHED DURING THE MID-WEEK PERIOD

Are you ready for spring? I know I am! The Arctic air masses keep coming as the highly amplified upper-level wind pattern continues. A high pressure ridge near the West Coast is pushing the jet stream way up to the north. This ridge has been keeping California exceptionally dry for this time of year. The jet stream then dives southeastward into the middle of the nation bringing with it brutally cold air masses that are just making this winter miserable for many folks. In addition, Alberta Clippers or low pressure disturbances are diving into the nation from Canada. Most of them are moisture starved at first but once they near the Gulf and East Coasts, they quickly pick up moisture and dump it in the form of snow, which we saw earlier this week. Due to the continued cold temperatures, the snow has stayed around much longer than it usually does here in Hampton Roads. The pattern will continue for most if not all of the upcoming week. Another Arctic Blast is expected to move into the Mid-Atlantic States Tuesday and Wednesday. Meanwhile, meteorologists will be keeping an eye on the development of a low pressure system that is expected to form off shore. It is uncertain whether this system will bring accumulating snowfall to our region. The computer models do not agree and their solutions are changing with each model run. So, stay tuned and monitor the local media and National Weather Service for the latest forecast and advisories over the next few days. Backing up to this weekend, a cold front may bring a snow flurry or brief shower today (Saturday) but no significant precipitation is expected. Sunday should be cold and dry. On Monday, a brief warm up is expected as we may see normal temperatures. But then, the bottom drops out again. That’s it for now. Have a good weekend!
