A NICE WEEKEND SEEMS LIKELY IN HAMPTON ROADS… AFTER A BRIEF WARM UP, WE COOL BACK DOWN

Saturday looks to be fantastic as high pressure remains in control of our weather. Temperatures rebounded nicely Friday afternoon after a frosty morning. A weak cool front will slip in from the north turning our winds to a more NE or E direction later in the weekend. This will cool us down a bit. Then, we have to see how close a low pressure gets to our area next week. Right now, the models do not bring that much moisture our way, but stay tuned. Saturday starts the new month and we should see more of an active weather pattern develop over the next few weeks as winter approaches. The jet stream normally migrates southward in November bringing more storminess to our nation. On average, the number of windy days increases during November. It’s not an especially wet month for our area but every November is different. I’ll have an update on Sunday.

DEEP UPPER-LEVEL TROUGH SPAWNS A LOW PRESSURE AREA NEAR THE MID-ATLANTIC REGION… COLD AIR RUSHES INTO THE SOUTHEAST BEHIND THE TROUGH

A large trough of low pressure has helped spin up a low pressure area which is causing some rain here locally. Although heavy rain is not expected, a period of steady light rain is likely Monday night. Things clear out on Tuesday as the low moves out to sea. The low will intensify as it moves away causing our winds to be quite strong through Tuesday. All in all, anyone heading out Monday evening will find it quite nasty. We stay on the cool side for a few days as the trough slowly lifts out. Temperatures should moderate as we head towards the weekend. After Monday night’s rain, no precipitation is expected until late in the weekend or early next week. However, it could remain dry into next week.

DRY WEATHER IS EXPECTED THIS WEEK… TEMPERATURES TUMBLE DURING THE MID-WEEK PERIOD BUT RECOVER AS WE HEAD TOWARDS THE WEEKEND

The frontal system that moved through on Saturday brought about a quarter of an inch of rain to my Virginia Beach neighborhood. Now, we are entering a dry period and aside from a sprinkle on Tuesday, we probably will not see any significant rainfall for quite a while, perhaps through next Saturday. A sharp cold front will┬ácause temperatures to tumble during mid-week but will slowly recover as we head towards next weekend. We still are running a deficit here in Hampton Roads so lets hope that this dry spell doesn’t last too long. Eventually storminess will increase across North America and we just have to hope that the storm track is more southerly this year. This will help to bring up Gulf moisture which plays an important role in our cold season precipitation. We haven’t received significant snowfall since 2004, so hopefully that streak is broken this winter.

A SOUTHERLY FLOW BRINGS WARMTH AND HUMIDITY TO HAMPTON ROADS… NOT MUCH RAIN FELL AND I DON’T THINK WE’RE GOING TO SEE MUCH ON SATURDAY… SUNDAY LOOKS GREAT… COLDER WEATHER MOVES IN FOR NEXT WEEK

A southerly flow ahead of an approaching cold front will make Saturday almost feel like a day in late┬ásummer. Although our official rain chances are 80% from the NWS, i don’t think that we are going to see much today across Hampton Roads. I’m not saying that it will not rain, I just don’t think that we will see that much. Just some occasional light rain will occur. Sunday looks dry for everyone as the front moves offshore. Another cold front will approach early next week bringing what should be the coldest air of the season. A significant dip in the jet stream will allow the cold air to flow into our region. No major precipitation events are expected this upcoming week. Note that the first major lake effect snow situation of the season is likely in some of the usual areas to the lee of the Great Lakes late Tuesday and Wednesday. Winter is on the way!

THE COOL WEATHER WILL BE GONE BY THE WEEKEND… A STORM SYSTEM FROM THE WEST MAY AFFECT THE MID-ATLANTIC STATES BRINGING A CHANCE OF SHOWERS… COLDER WEATHER SEEMS LIKELY NEXT WEEK

A cool high pressure area has moved into the region and will control our weather through Thursday. A low pressure system from the center of the nation combined with moisture moving up from the tropics should bring us some shower activity over the weekend. Temperatures will slowly moderate as we head towards the weekend. Friday will be a transitional day with clouds increasing. By Saturday, we should see some showers and there may even be a little thunder, too. How much rain we receive depends on how much tropical moisture that this system can tap. A steady rain may even occur if everything comes together. After the low moves out on Sunday, we should dry out. A chilly airmass may arrive some time next week.
