10/22 – Brantly’s “Above-Normal Temperatures Continue” Thursday Morning Forecast


The nose of a ridge of surface high pressure remains rooted at the beginning of the period over the southeastern United States. This nose of high pressure gets erased as a weak upper level shortwave trough continues to move across the southern U.S. Saturday.

Scattered to at times numerous showers and thunderstorms are expected over the region Friday afternoon and evening before tapering to isolated to scattered with loss of daytime heating Friday night. Saturday once again ramps up rain chances, with scattered showers and thunderstorms once again expected across the region.

Forecast models vary with convective coverage Saturday, and thus have maintained 30 to 40% Rain chances over the area. An interesting trend in the models has been for the weak upper level area of low pressure to dig slightly more than forecast, which may help give us an additional boost in rain activity over the area as it moves through. This trend will have to be monitored for any potential future increases in Rain chances for the day Saturday. Any rain chances should effectively come to an end by late Saturday evening across the area.

Temperatures will remain above average for the most part despite increased cloud cover and rain chances during the period. Expect lows Friday night in the upper 60s to lower 70s across most areas, with possibly middle 60s over our northwestern counties. Highs Saturday may struggle some reaching “only” the upper 70s to lower 80s.

Comparatively, our average highs this time of year are in the middle 70s for most locations, and our average lows are in the lower to middle 50s. Lows Saturday night play a similar tune as the previous night, making it into the upper 60’s to lower 70s, with middle 60s across our far inland counties.
