AFTER A CHILLY WEEKEND, TEMPERATURES SHOULD WARM UP BY MID-WEEK AND PRECIPITATION CHANCES WILL GO UP… A COLD FRONT WILL DROP TEMPERATURES AGAIN LATER IN THE WEEK

High pressure will keep us dry and on the cool side today (Sunday), but a warm-up is on its way. Temperatures by mid-week may reach the 70’s! Along with the warmer weather may come a chance of rain, which will be due to increasing moisture out ahead of an approaching cold front and an associated trough. I hope that we see more rain with this next system than we did with the one on Friday. This Wednesday (Dec 1st), it will be four weeks since we’ve received significant precipitation. However, as I said in my Saturday’s post, precipitation for the year is running above normal due to the heavy rainfall that we saw last summer. The air mass that will move in behind the cold front will be quite chilly so the week will end on the cool side. Thanks for reading and have a great day.

THE WEEKEND WILL BE A CHILLY ONE FOR HAMPTON ROADS, BUT WE SHOULD SEE PLENTY OF SUNSHINE… RAIN CHANCES INCREASE AS WE HEAD TOWARDS THE MIDDLE OF NEXT WEEK

The cold front that moved through the Mid-Atlantic States on Friday didn’t bring much rainfall with it to most of Hampton Roads. That was no surprise as a westerly downsloping wind flow caused the precipitation to lessen as the system crossed the Appalachian Mountains. November will turn out to be a very dry month overall as we’ve only picked up a little over a half inch of rainfall this month. However, one must keep in mind that for the year, we are still running well above normal. The chilly air mass will be around for the entire weekend and a slight warm up is expected as we move towards mid-week. Rain chances will begin to rise on Tuesday ahead of the next frontal system. I hope that we will see higher rainfall totals with this system than we saw with Friday’s frontal passage. With all the dead leaves on the ground, we do not want to see conditions get too dry. All you need is a period of windy weather and with the low humidity levels that are common at this time of year, the fire danger could increase rapidly. As I stated in my post from Thanksgiving Day, this is common during a La Nina period. I’ll have an update on Sunday morning. Thanks for reading.

THANKSGIVING DAY LOOKS NICE OVERALL… BLACK FRIDAY COULD BE A BIT WET, BUT IT WILL BE MILD EARLY IN THE DAY WITH TEMPERATURES FALLING LATER ON… COLDER AIR RETURNS FOR THE WEEKEND

Happy Thanksgiving! It should be a great day for anyone who still has to travel today. No weather related issues will impact your travel in Hampton Roads. However, up to our north and west, it may be a different story as some rain is expected. High pressure is going to keep us dry for the most part, but a sprinkle can’t be ruled out. Warmer air will surge in tonight out ahead of a cold front. Friday should start out okay but there will be an increasing chance of showers as the cold front draws closer. Rainfall amounts aren’t expected to be significant, however. Behind the cold front, winds will turn to the NW and will usher in much cooler air for Saturday and Sunday. Dry conditions should prevail over the weekend. Speaking of dry, do you know that it has been three weeks since we’ve had significant rain? With the La Nina in the Pacific, this is a typical scenario, where low pressure systems track to our north and west at this time of year. The ridge over the Southeast might break down temporarily allowing troughiness to produce higher rain chances over the next several weeks, but we’ll have to wait and see if that actually happens. In the extended forecast, rain chances increase by mid-week.

THE GREAT WEATHER CONTINUES THROUGH WEDNESDAY… THE THANKSGIVING WEEKEND FORECAST IS FAR FROM CERTAIN

There is not a lot to discuss about the current weather pattern. But who’s complaining? High pressure continues to control the weather here in the Mid-Atlantic States and the only changes seem to be the wind direction and subtle day to day temperature variations. Sunshine has been abundant and will continue to dominate the weather into the new work week. Then, the weather becomes difficult to predict. There will be a cold front approaching the area by mid-week, but this front is expected to be weakening as it moves into the region. This primarily is due to the high pressure ridge in the Southeastern States, which is not allowing cold air masses to infiltrate that far southeastward. This is typical of La Nina periods. (La Nina is the cooling of the Eastern Pacific Equatorial waters which change the weather patterns across the U.S.). When will the weather pattern change and when will our spell of great weather end? Right now, it appears that we will have some unsettled weather as we head into the Thanksgiving weekend. But how much rain and cloudiness that we will see is far from certain at this time. Meanwhile, a storm system out west is causing mountain snow which is a good thing for ski resorts out that way as well as their future water needs. Anyway, enjoy this tranquil weather while it lasts. Thanks for reading.

THE WEEKEND LOOKS GREAT FOR MID-NOVEMBER… AFTER A BRIEF COOL DOWN ON FRIDAY, MILD WEATHER RETURNS ON SATURDAY

Another fantastic weekend lies ahead for Hampton Roads. The weather pattern is really quite benign. At the time of this writing, precipitation is hard to find east of the Rocky Mountains. While it is quiet in the east, cold air is building in Central Canada. Eventually, this cold air mass will be plunging into the U.S. I’ll have more on that in my weekend posts. I’ll also provide an extended outlook for the Thanksgiving weekend, which is looking a bit wet at the start. The low pressure that moved west of us earlier this week didn’t bring much rainfall to most of Hampton Roads. My backyard picked up only a trace of rainfall. I’ll have an update Saturday morning. Thanks for reading!
