A SUMMER-LIKE WEATHER PATTERN TAKES OVER BRINGING HOT AND HUMID CONDITIONS TO THE MID-ATLANTIC STATES… ISOLATED TO SCATTERED THUNDERSTORMS WILL BE POSSIBLE, ESPECIALLY TOWARDS THE END OF THE WEEK

Summer arrives officially this Saturday, June 21st. High pressure taking up residence off the Southeast Coast will produce a southwesterly flow and it will feel like summer this entire week. The wind blows clockwise around areas of high pressures in the northern hemisphere. Dew points hovering around the 70 degree mark will make it feel uncomfortable for most of us. (See my Weather Fact entitled “What is the Dew Point and Why is it so Important?”). With all the heat and humidity around, it won’t take much to trigger a thunderstorm, especially during the afternoon and evening hours. An isolated thunderstorm is possible each day, but odds are, you will not see rain until we get closer to the end of the week. At that time, a backdoor cold front should be approaching and instability is expected to increase. The NWS has stated that there is some uncertainty with the extended forecast as they aren’t sure how much progress the front will make. If the front doesn’t make it this far south, we will be stuck in this hot and humid weather pattern for quite a while. Keep in mind that any thunderstorm that develops can be quite strong and even severe… Did you see the video from Nebraska of the twin tornadoes? That was absolutely incredible footage. Unfortunately, those tornadoes did major damage and were deadly… Regarding the tropics, the Atlantic Basin is quiet so no worries about tropical cyclones just yet. It’s still very early so this is quite normal. Once we get to late July and early August, hurricane season usually starts to ramp up. However, an early season storm sometimes occurs depending on the weather pattern. That’s it for now. Please be careful if you are working outdoors and make sure you take breaks and drink lots of fluids. Have a great day!

AFTER THE HEAVY RAINFALL ON FRIDAY IN PARTS OF HAMPTON ROADS, SKIES WILL CLEAR MAKING WAY FOR ANOTHER GREAT WEEKEND… TEMPERATURES AND HUMIDITY LEVELS WILL RISE AGAIN EARLY NEXT WEEK

The timing is absolutely amazing. A cooler and less humid air mass is moving into the Mid-Atlantic States just in time for the weekend thus extending the string of nice weekends here in Hampton Roads. A northerly breeze will take over today (Saturday) and you will notice the more comfortable conditions. Rain chances will be very low this weekend so outdoor plans should not be impacted by the weather… Over an inch and a half of much needed rain fell in my neighborhood Thursday and Friday. There was even some hail reported in parts of Hampton Roads late on Friday including my neighborhood. Since it is now the middle of June, you know that low humidity and pleasant temperatures cannot last that long. As the high pressure that is responsible for the nice weather moves offshore early next week, the clockwise flow around the high will bring a southerly flow into our region. This will bring back the humidity and the warmer temperatures. By the middle of next week, we may see an increased chance of isolated to scattered thunderstorms… The Tropical Atlantic remains quiet… Happy Father’s Day to all the dads out there!

WARM AND HUMID CONDITIONS WILL PERSIST THROUGH THE END OF THE WEEK… WITH ALL THE HEAT AND HUMIDITY AROUND, SHOWERS AND THUNDERSTORMS WILL BE A POSSIBILITY

Well, the low humidity and pleasant weather of this past weekend are now a distant memory. A warm and very humid air mass has overspread the Mid-Atlantic states and it’s not in a hurry to leave. Dew points are above 70 which means that it will feel quite uncomfortable for most of us. In an air mass like this, it doesn’t take much to produce showers and thunderstorms. However, forecasting exactly when and where they will occur is very difficult in our current weather situation. Upper-level disturbances, weak frontal boundaries, daytime heating, etc. are all potential triggers for convection. However, no rain has fallen in my neighborhood so far this week. In addition, not much rain has fallen in several weeks, which has resulted in rather dry conditions. Some areas have seen rainfall, such as Northeast N.C., especially during the early morning hours the past couple of days. The overall weather pattern is expected to remain the same into the first part of the weekend… The Tropical Atlantic is quiet for now.

HAMPTON ROADS WILL HAVE ANOTHER BEAUTIFUL WEEKEND AS HIGH PRESSURE BUILDS INTO THE REGION… UNSETTLED WEATHER SEEMS LIKELY NEXT WEEK

Our string of nice weekends continues as high pressure builds in from the northwest. There will be some clouds at times but no significant precipitation is expected here in Hampton Roads. High temperatures should be in the lower 80’s, but it will be cooler near the water due to an onshore flow. Increased humidity combined with weak frontal systems are expected to bring us a period of unsettled weather beginning later Monday and it could last until the end of the week. At this point, it’s very difficult to nail down the timing and coverage of the rainfall. The NWS increases our rain chances beginning Monday night… Since it is now Hurricane Season, I will try to keep you posted on any potential development. The only area right now of any concern is in the southwestern Gulf of Mexico. At the current time, chances are very low that a tropical cyclone will develop in the next 48 hours. That’s it for now. Enjoy the great weather this weekend!
