WARM AND HUMID WEATHER ARE EXPECTED FOR THE NEXT FEW DAYS WITH THE CHANCE OF SHOWERS AND THUNDERSTORMS INCREASING ON MONDAY AND TUESDAY

We are entering the time of year when humidity levels reach a point that any weather disturbance can cause a shower or thunderstorm to develop at almost any time of the day. Of course, the afternoon and evenings are prime time for storm development. This is primarily due to daytime heating from the sun. Instability levels normally reach their highest point in the afternoons. However, sometimes showers and storms develop in the late night and early morning hours when conditions are right and the flow aloft supports development of convection. Warm fronts moving through the area sometimes cause our morning rainfall at this time of year, especially when very humid air masses move into the region. However, as I stated earlier, afternoons and evenings are when we normally see the storms develop.¬†The current weather pattern today (Sunday) is one where we could see a shower or storm develop, but coverage isn’t expected to be that extensive today according to most weather forecasters. Our chance of rain will ramp up somewhat on Monday out ahead of an approaching front well to our west. A rather moist flow from the south and southwest ahead of this front will make for ideal conditions for heavy rainfall in some areas Monday through Tuesday. Rain chances are forecast to decrease on Wednesday only to return later in the week. If this forecast holds, I don’t think that your lawn will need to be watered for a while. The tropical Atlantic is quiet for now.

IN THE WAKE OF TROPICAL STORM ANDREA, A WEAK DISTURBANCE MAY BRING A FEW SHOWERS AND THUNDERSTORMS TO THE REGION… THE WEEKEND SHOULD BE DECENT OVERALL DESPITE THE CHANCE OF A SHOWER OR STORM

As the heavy rain from Post Tropical Storm Andrea heads into the Canadian Maritimes, a weak disturbance in its wake combined with a frontal boundary may bring a shower or thunderstorm to parts of Hampton Roads today. Severe weather isn’t expected but a few of the storms could be on the strong side. Rainfall totals from the tropical storm varied across Southeast Virginia. The interaction between the very moist tropical flow of air from the southeast running up against a frontal boundary located roughly along I-95 caused very heavy rain amounts just to the west of Hampton Roads. About an inch of rain fell in my Virginia Beach neighborhood. As the storm moved northeastward, flooding rains occurred in the NYC metro area. and in parts of New England.¬†Other areas of the Northern Mid-Atlantic States and Northeast reported flooding. Wind wasn’t a huge problem with this storm as expected. The weekend shouldn’t be that bad with high temperatures in the low to mid 80’s and just a chance of a shower or storm. Rain chances will remain with us into early next week but any showers or storms should be isolated or scattered for the most part… The tropical Atlantic is quiet for now.
