AFTER A CHILLY START, SATURDAY WILL TURN OUT TO BE A VERY NICE SPRING DAY… DRY WEATHER SHOULD PERSIST FOR SEVERAL DAYS

The national radar this morning shows very little precipitation across the country as the weather map is quite benign. This is shaping up to to be a great weekend for Hampton Roads. With winds becoming onshore, high temperatures will be cooler near the coast. Note that the water temperature is still in the 50’s. The only challenge in the forecast is what the effects that a back door cold front will have on our weather this upcoming week. No significant precipitation is expected with this front, and actually, the entire week should be dry for the most part. The pollen will probably start to cover everything again but once the trees are fully in leaf, the tree pollen season will subside. That’s about all I have, so enjoy this nice spell of weather that lies ahead. I’ll have an update on Sunday morning.

SKIES SHOULD CLEAR ON FRIDAY… TEMPERATURES WILL BE MUCH COOLER AND WE SHOULD REMAIN DRY FOR THE NEXT SEVERAL DAYS

A cold front that moved through overnight has pushed the warm air out to sea. It also brought us rain which washed the pollen away at least for now. About three quarters of an inch fell in my backyard overnight. We will not see highs in the 80’s for quite some time and we probably won’t see significant rain for at least a week. It will be a bit breezy today (Friday) but winds should drop off tonight and stay on the light side this weekend. It really looks like a nice weekend. I’ll have an update on Saturday morning.

THURSDAY IS THE FINAL DAY OF THE WARM WEATHER… SHOWERS AND THUNDERSTORMS ARE LIKELY THURSDAY NIGHT INTO FRIDAY MORNING… COOLER WEATHER FOLLOWS

Well, the early spring warm spell is about to come to an end thanks to an approaching cold front from the west. This front will probably give us a decent shot of rain Thursday night. There may be some thunderstorms which may reach severe limits in some spots. After the front clears the coast on Friday, we should slowly clear out. Cooler weather behind the front means a return to normal and possibly below normal temperatures into the weekend. Isn’t it amazing how not that long ago, it was chilly and we all had our heating systems on, and the past few days some folks had their air conditioners going? The rain should wash some of the pollen away, but we still have a way to go before the tree pollen season is over. I’ll have an update on Friday.

THE GREAT SPRING WEATHER CONTINUES… TEMPERATURES SHOULD TREND HIGHER TOWARDS MID-WEEK… RAIN CHANCES INCREASE LATER IN THE WEEK, BUT THERE IS UNCERTAINTY AS TO HOW WET IT WILL GET

High pressure is controlling our weather and will continue to do so for the next few days. Easter Sunday will be superb with plenty of sunshine. A weak cool front crossing the region shouldn’t bring anything more than a few clouds to SE VA. Temperatures should trend higher as we get towards the middle of the week. The next significant system to affect our area is giving the computer models a tough time. One model paints a rather wet scenario for us on Thursday and Friday while another is not quite as wet. Enjoy the early spring weather while it lasts. It’s giving us the opportunity to dry out after a very wet late winter season. I’m seeing reports that the El Nino will soon be a thing of the past and that there may actually be a La Nina developing by the time the summer comes. That should help to change our pattern to a drier one by mid-summer, but of course, this is not certain. Predicting long term weather patterns is not at all an exact science. Speaking of long term forecasts, some meteorologists out there are saying that there is going to have a very active hurricane season in the Atlantic basin. Only time will tell. That’s it for now.

AFTER A CLOUDY AND FOGGY START, SATURDAY IS EXPECTED TO TURN OUT QUITE NICE, BUT THERE WILL BE A LARGE TEMPERATURE DIFFERENCE ACROSS THE AREA

High pressure off the East Coast is producing a light onshore flow which has brought in low clouds and fog to Hampton Roads, especially in areas closest to the water.  Keep in mind that the water temperature is still very chilly, so a breeze off of the water can keep temperatures quite cool in coastal areas. In addition, the lower temperatures cause the water vapor in the air to condensate, which is why we have fog and low clouds in some areas this morning. The April sun is strong so forecasters are expecting clearing later in the morning. Sunshine is expected later today. Sometimes, these setups can be quite challenging for weather forecasters. We’ll see if their forecast verifies. There is expected to be a huge temperature contrast across the area, similar to Friday. Temperatures along the coast are expected to be in the 60’s and temperatures inland could go well into the 80’s! The wind direction determines everthing at this time of year. The wind direction is expected to be out of the South or Southeast for most of the day. On Sunday, a weakening front approaching from the west could cause a shower in some spots. Fair weather is expected to continue into early next week. I’ll have an update on Sunday.
