THIS WEEKEND COULD BE ONE OF THE NICEST OF THE SUMMER… THE TROPICS REMAIN QUIET… CAN THIS HURRICANE SEASON STILL BE AS ACTIVE AS WAS EARLIER PREDICTED?

The high pressure area over New England that pushed a cold front through the Mid-Atlantic States is responsible for possibly bringing one of the best weekends of the entire summer to Hampton Roads this weekend. A light onshore flow will keep temperatures tolerable and humidity levels won’t be as high as they have been of late. One thing to keep in mind and be cautious about… With water temperatures at their warmest of the year,  a breeze off the water can bring in higher humidity values. However, the air is originating off of the cooler New England waters and for the most part, the air should not pick up enough water vapor to cause too many problems. Some patchy morning fog and even an isolated light shower cannot be ruled out but overall I think that you will enjoy this weekend. One downside is that the rip current threat will be high on Saturday due to the persistent onshore flow. It should lessen a bit on Sunday. The high pressure moves further off of the coast by Monday and Tuesday so this could bring an increased chance of an isolated thunderstorm… What is going on with the tropics? Despite it being the middle of August, there isn’t even a suspicious area that forecasters are watching. What happened to this hurricane season, which was supposed to be so active? Forecasters have their theories, but right now, we have to wonder whether it will pick up quickly and still be an active season. Nobody knows what will happen, but let’s enjoy the peaceful conditions while they last. I’ll have an update on Sunday.

THE HEAT RETURNS THIS WEEK… TROPICAL STORM COLIN IMPACTS BERMUDA

With an upper-level high pressure ridge rebuilding to our west, another spell of hot and humid weather seems likely here in Hampton Roads this upcoming week. Temperatures are expected to reach the mid to upper 90’s by mid-week in the inland areas. Although there will be a chance of a thunderstorm, especially during the afternoons and evenings, dry weather is expected for much of the week. Keep in mind that with all of the heat and humidity around, any storm is capable of producing heavy rain, frequent lightning, and strong gusty winds. A cold front may affect our region late in the week or next weekend. This may result in a more organized area of showers and storms… Tropical Storm Colin is impacting Bermuda today (Sunday) and is actually bringing much needed rainfall to the island. I’ve seen reports that it has been dry there of late so this may be a good thing for them. Since the storm has remained weak due to shear and some dry air infiltration, no major damage is expected. That’s really all I have for now. Get ready for another round of uncomfortable weather which we all should be used to by now. Remember to drink plenty of water if you are working (or playing) outdoors and try to stay cool.

TEMPERATURES THIS WEEKEND WILL BE A LITTLE COOLER… TEMPERATURES MAY HEAT UP AGAIN TOWARDS MID-WEEK… TROPICAL STORM COLIN MAY IMPACT BERMUDA

A cold front is slowly sinking southward through the Carolinas. The onshore flow north of the front will bring cooler temperatures to Hampton Roads. We should also be rainfree today (Saturday). However, south of the VA/NC border, a shower or storm is possible. If you’ve been putting off doing yard work (or any other outdoor work) due to the hot and humid weather, this weekend is the time to get out there and get it done. Why? Well, forecasters believe that the heat will be back again by mid-week. I was out of town on Thursday when the thunderstorms moved through Hampton Roads but I understand that they were quite intense in some areas. My rain gauge had about a half inch when I got home late yesterday. I was in Charlottesville, VA on Thursday and they had a very strong thunderstorm move through that area. Power went out in the restaurant that my family was eating in that evening. There was quite a bit of damage to trees from that storm. Tropical Storm Colin is expected to move N-NE towards Bermuda bringing beneficial rainfall to that small island. The storm is currently disorganized but it may strengthen due to the expected relaxation of the shear that has been affecting the storm the past few days. I should have an update on Sunday.

FORECASTERS ARE PREDICTING THAT THE HEAT WILL RETURN ON WEDNESDAY… TROPICAL STORM COLIN DEVELOPS IN THE CENTRAL NORTH ATLANTIC

Today (Tuesday), we should see more sunshine as high pressure builds southward from off the coast of New England. The clockwise flow around the high will eventually produce a SW wind, which will pump up heat and humidity back into the Mid-Atlantic States. Enjoy today as it will soon become uncomfortable for many of us. I actually enjoyed the period of cloudy weather Sunday and Monday as it was a refreshing change from the heat that we’ve been experiencing the past several weeks. Yesterday a small area of showers delivered about 0.40 inches of rain to my Virginia Beach neighborhood. Forecasters don’t think that we will see any organized rainfall today, but an isolated shower/storm cannot be ruled out. The peak of this next period of hot weather appears to be Thursday. Then, a cold front may approach the area as we head towards the weekend… Tropical Storm Colin has formed in the Central North Atlantic. The storm is weak now but it is expected to strengthen as it tracks to the W-NW. A slow turn to a more NW track is expected but stay tuned on this. There seems to be some model disagreement as to the storm’s future track. This is a good time to dust off your hurricane tracking map and also to ensure that you have all the supplies needed should a storm hit this area. I’m not saying that this storm will hit the east coast, but early August is usually the time when the frequency of tropical cyclones increases. .

A MOIST EASTERLY FLOW KEEPS THINGS A BIT UNSETTLED ON MONDAY… THE WEATHER HEATS UP BY MID-WEEK AS OUR WINDS SHIFT TO A MORE SOUTHERLY DIRECTION

High pressure off the New England coast is causing a light easterly wind flow off the water. This combined with a weak trough off the NC Coast will bring us slightly unsettled weather today (Monday). These conditions caused an overcast to hang tough all day on Sunday. Temperatures remained in the 70’s which was a welcome break from the intense heat that has plagued our region for weeks. I actually was able to shut my air conditioner off and open my windows. I haven’t been able to do that in a very long time. Will it rain a lot today? Forecasters don’t believe it will. However, a shower cannot be ruled out at any time. The radar at 10:10 AM shows showers continually developing from the Back Bay northward to the Eastern Shore. Movement is N-NW. This could bring a good dose of rain to some localized areas. Tuesday should be a warmer day as the wind direction is expected to have more a southerly component. Indications are that we will see more sunshine on Tuesday. (Vacationers, keep your fingers crossed). This will be a result of the high off the New England coast building southward. Then, our weather starts to heat up on Wednesday and we should see a continuation of the heat and humidity through the end of the week. A shower or thunderstorm is possible each day. What about the tropics? The area in the East-Central Atlantic that forecasters are watching has a 90% chance of developing into a tropical cyclone according to the NHC. I’ll have an update on Tuesday.
