THE WET WEATHER IS OVER FOR NOW AND BY MID-WEEK, WE MAY HAVE MORE RAIN… MONDAY WILL BE A SUNNY DAY BUT ON THE BREEZY SIDE… TEMPERATURES SHOULD BE AT SEASONAL LEVELS

Well, I picked up another 0.40 inches Saturday night making the total for the weekend 1.20 inches. The large low pressure system that has been responsible for the blizzards and severe weather is slowly moving through the Great Lakes region and it’s associated cold front will be crossing our region later today. Right now (Sunday morning), we are in the warm sector of this large storm system. For you weather enthusiasts or for anyone studying meteorology, it’s really a classic looking storm on the weather map with the occluded front and all of the isobars surrounding the low. The pressure gradient associated with this storm system will create our breezy/windy conditions through Monday. Monday should feature plenty of sunshine and actually we should start seeing the sun later today (Sunday). Tuesday should be nice, also. However, the active pattern is expected to continue and yet another low pressure system will be approaching on Wednesday. As a result, we should see some rain or showers some time on Wednesday but it is way too soon to get into any detail on that system.

ANOTHER ROUND OF RAIN IS ON THE WAY… WILL WE SEE SEVERE WEATHER?… WHEN WILL THE UNSETTLED WEATHER PATTERN END?

One round of wet weather is now (Saturday morning) moving out to sea as a weak low moves away. A more potent system is now developing well to our southwest and this system is expected to bring us another round of wet weather tonight and into Sunday morning. Thunerstorms are a distinct possibility along with the chance of a severe thunderstorm. Instability will be increasing throughout the night so please stay tuned to the local media and NWS for the latest updates. The wet weather should move away on Sunday. Temperatures will be on the mild side throughout the weekend in our southern zones. Areas to the north on the other side of the front will be a bit cooler. I picked up about 0.80 inches of rain overnight and more is expected tonight making the month of March an above normal month precipitation wise. Once this next system moves away on Sunday, we should have a few days to dry out. I noticed that my weeds are getting quite high in my backyard so hopefully I’ll be able to do some yard work on Sunday afternoon. Is the warm weather here to stay? Well, there will still be some cold air intrusions into the US, especially in the middle of the nation, over the next several weeks, but how much of the cold air makes it east is questionable. We’re getting to that time of year when the polar and arctic air masses moderate quite rapidly due to the high angle of the early spring sun. You’ve probably seen on the news the wild weather conditions occurring from the Northern Plains down through the Gulf Coast states. There have been blizzard conditions, tornadoes, river flooding, and very heavy rain reported in those areas. Note that blizzards are typical for early spring in the Rockies and the Plains States. I’ll have an update on Sunday.

THE UNSETTLED WEATHER PATTERN CONTINUES THROUGH EARLY SUNDAY… THUNDER IS POSSIBLE SATURDAY NIGHT… TEMPERATURES RISE ON SATURDAY

Just a quick update on the current weather situation here in Hampton Roads… A warm front is currenly moving through the region causing some rain on this Friday evening. The rain will come to an end late at night but don’t put your umbrellas away just yet. A low pressure system is expected to develop over the Southeastern States on Saturday and this combined with a cold front approaching from the west should cause rain showers to return to the region late on Saturday. There is even a chance of thunderstorms Saturday night as instability increases. Warm air will be surging in ahead of the cold front making Saturday the warmest day we’ve seen in several days. After this next round of wet weather, we should dry out later on Sunday. I’ll have an update on Saturday on the severe weather potential and I’ll look at the extended forecast.

MILDER AIR IS ON THE WAY BUT SO IS THE RAIN… UNSETTLED WEATHER SHOULD CONTINUE THROUGH THE WEEKEND

After a very chilly morning on Wednesday, clouds will slowly increase but the rain should hold off until early Thursday morning. The cold high pressure system that is centered over Eastern Canada but has been ridging down into the Mid-Atlantic States is finally going to release its grip on our region.  A slow moving frontal system will be approaching Hampton Roads and this should make for a wet Thursday although forecasters don’t anticipate a lot of rain… just some light rain at times. The forecast is very tricky for Friday through Sunday. Clouds will most likely dominate but exactly how much precipitation we receive and when will it occur are the difficult questions. Currently, the thinking is that we will dry out a bit for Friday, but rain chances should increase on Saturday and last into Sunday. Although we’ve received plenty of rainfall this month, we are still running below normal for the year. So, the bottom line is that we warm up a bit on Thursday but we also will see plenty of clouds and some rain is likely and the weekend looks unsettled, too.

WHEN WILL IT FEEL LIKE SPRING?… WET WEATHER SEEMS LIKELY ON AND OFF LATER THIS WEEK AND INTO THE WEEKEND

A warm up is on the way, but we’ll have to pay the price with some wet weather. The cold high pressure area over Eastern Canada that has been nudging down into the Mid-Atlantic States will slowly weaken and move out to sea. Tuesday will be another chilly early spring day, especially near the coastline. Then, the wet weather that has been out to our west will begin to affect our weather. Wednesday should be another dry day but clouds will be on the increase. By Thursday morning, the unsettled period begins. It may last through Sunday and possibly into Monday. Now, it won’t rain all the time during this period, but we will have several opportunities for rain, with the first occurring on Thursday. Temperatures won’t be as chilly as they have been during this period. The weather out west has been very active of late, with severe weather and even a blizzard affecting some areas. Expect episodes of the severe weather to continue in spots over the next few days. I’ll have an update on Wednesday.
