It's a great start to our Friday morning across the GTR. Here's a look at the high-resolution RPM for 4pm this afternoon. Notice there should be only isolated coverage of showers and thunderstorms by this afternoon. The more concentrated areas of showers and thunderstorms should be over the far northern Gulf into the Florida Panhandle due to a weak tropical disturbance.
As advertised, the models continue to suggest a ridge of high pressure aloft will build in from the west by the end of the weekend persisting into the first part of next week. Normally, this would mean increasing surface temperatures across the area, but as high pressure at the surface noses in from the northeast, a more easterly to east-southeasterly flow is expected to prevail. As this happens, I think this will help keep temperatures mostly in check, i.e. not getting into the upper 90s. I think temperatures through the end of the weekend through the first part of next week should range from about 89 to 94. Also, rain chances should be minimal (at or below 20%) through the weekend into the first part of the week.
By the end of the week, the GFS model shows the ridge of high pressure shifting back towards the west and we come under a northerly flow aloft. The Euro shows this too, but has the trough axis a little farther to the east toward the Mid-Atlantic. In either case, I think rain chances will slowly creep back up to near seasonal/climatological levels by mid-week as upper heights begin to decrease ever so slightly.
Have a great Friday, and God Bless!
