| Area Forecast Discussion National Weather Service Tallahassee FL Issued by National Weather Service Houston/Galveston TX 1021am EDT Wednesday Oct 21 2020 .NEAR TERM [Thursday Through Friday]... Low clouds have lingered a bit longer this morning over much of the region, although general breaking up/some clearing will develop into the early afternoon. The lingering low clouds have also hindered heating a bit so far, although temps will quickly rebound as the clouds break up. Still looking for a mild late Oct day with highs topping out well into the 80s. Otherwise, forecast left untouched with chances of a few showers increasing this afternoon mostly over southern GA and the FL Bend region. Evans Near Term - Through Tonight A weak mid-level disturbance over the eastern Gulf and Florida peninsula will move slowly northward over the next 24 hours as easterly flow continues to keep a moist airmass in place. Low clouds this morning will gradually lift, and daytime heating in conjunction with the weak mid-level disturbance is expected to result in scattered showers and isolated thunderstorms developing across the region. Initial development is expected across south central Georgia later this morning, then spreading westward through the afternoon hours. Rain chances with this scattered activity are generally expected in the 30-50% range for most of the area today with activity diminishing quickly after sunset. High temperatures will generally be in the low to mid 80s with overnight lows in the upper 60s to lower 70s. .LONG TERM [Friday Night Through Wednesday]... As easterly to southeasterly flow persists across the region through the weekend, the aforementioned moisture laden airmass with PW values (Precipitable Water values) between 1.6-1.8 inches is expected to persist during this time. Shower and thunderstorm activity is expected to be remain scattered to isolated in nature as only weak forcing for ascent is expected during this time. The best chances for widespread rain and upper level forcing is over the weekend as a weak upper level vorticity maxima propagates across the southern tier of the country into the Southeast during this timeframe. This is expected to create a very broad trough axis over the region this weekend, and provide a focus for afternoon shower and thunderstorm activity. Behind this weak trough, a rather strong trough over the western conus develops, and causes strong to moderate upper level ridging over the eastern conus during the early part of the next work week. This ridging will generally lead to lower Probability of Precipitation chances through early next week. Overall highs will be warm with temperatures climbing into the mid 80s consistently over the next several days. Lows are expected to be warm as well in the upper 60s to near 70, with the excess moisture hanging around in the low levels from the previously discussed southeasterly flow. Marine Breezy easterly winds around 10-15 knots are expected to persist through the remainder of the work week. These winds will lead to rougher than normal seas, with swells in the 2-4 foot range expected. Although advisory conditions are not expected to be met, small craft should exercise caution through the remainder of the week, as winds could occasionally gust to 20 knots or greater. Fire Weather Red flag conditions are not expected for the next several days. Hydrology Rain chances are expected to increase over the next several days; however, given that overall rainfall totals expected over this time frame are less than a quarter of an inch, there are no river flooding concerns. A few isolated heavier rain showers could develop over the next few days, which may lead to localized heavier amounts between 1-3 inches; however, given the recent dry conditions, there are currently no flooding concerns.
