7/21 – Rob’s “Changing Pattern” Wednesday Morning Forecast
A frontal boundary remains stalled from the Carolinas to southeast Texas, with a weak impulse of low-pressure currently over south central Louisiana. The boundary will remain stalled over the area today thus widespread showers and thunderstorms will develop along it once again. The boundary will slowly shift north and wash out by Thursday afternoon. High-pressure over the mid-section of the country will build slowly eastward by Thursday bringing lower rain chances and a return to normal to slightly above normal temperatures by Friday.
A weak disturbance off the Florida east coast will shift slightly west on-shore this weekend into Florida/Georgia. With the additional tropical flow, mainly east of the area, showers and t-storms will be on the increase once again but mainly during the afternoon. Temperatures could climb into the lower 90s over the weekend with scattered showers and storms expected through the period. Upper level high-pressure parked over the middle Mississippi Valley through the middle of next week will bring much drier and hotter temperatures with highs in the lower to middle 90s.
