THE FRONT WHICH HAS BEEN TRIGGERING SHOWERS AND STORMS THE PAST FEW DAYS STRUGGLES TO FINALLY PUSH OFFSHORE… THE TROPICS ARE QUIET FOR NOW

Late Saturday afternoon and evening, a line of moderate to heavy rain moved through Hampton Roads. There was no lightning or thunder in my neighborhood. Around a half inch of rain fell in my backyard. The frontal system that has been responsible for the unsettled weather of late is finally going to limp offshore but not before bringing yet another day with a chance of showers and thunderstorms. Forecasters are saying that the chances of rain today (Sunday) are lower than what they were on Saturday. The further southeast you are, the greater the chances of rain. On Monday, the front should be just offshore and weakening, but a sea breeze might be enough to set off an isolated shower/storm. Another front may bring another chance of a round of showers/storms Tuesday into early Wednesday. Odds are that the coverage and duration won’t be as high as it was the past few days. Fronts have a very tough time moving through our part of the country at this time of year.┬áSome of the reasons for that are the Bermuda High pressure off the Southeast Coast and the normally weak upper-level flow… The tropical Atlantic has quieted down for now but we are soon going to be entering the time of year when conditions should improve for tropical cyclone development. Right now, it seems that dry air, wind shear, and overall stable conditions are combining to inhibit tropical cyclone development. The water is plenty warm enough to sustain a hurricane so once the hindering factors are gone, it will be very interesting to see how active it will become. That’s it for now. Have a great day.
