Area Forecast Discussion National Weather Service Tallahassee FL 1041 AM EDT Thu Oct 1 2020

UPDATE.

No changes were made to the previous forecast.

PREV DISCUSSION [649 AM EDT].

NEAR TERM [Through Tonight].

Another cool, dry day is in store to begin the month of October. A post-frontal airmass remains in place over the area, with surface high pressure to the west ushering in northwest flow. A secondary cold front (albeit drier than its predecessor) is forecast to swing down tonight as a northern stream upper trough becomes more established across the eastern US. These features should bring a reinforced shot of cool, dry air from the northwest, keeping rain suppressed. Little to no clouds are expected through the period.

Calm winds overnight become northwesterly at around 5 kts during the afternoon, then veer to the north-northwest this evening with the arrival of the aforementioned front. Slightly warmer high temperatures are forecast today (low 80s) as mostly sunny skies prevail. Since Wed's low temperatures were slightly lower than forecast, (especially for the western 1/3 of the CWA), and similar early-morning conditions are expected Thurs, decided to reduce min T by a couple of degrees (mid/upper 50s areawide) after blending NBM and CONSAll guidance.

For October 2020, the CPC predicts below-average temperatures and equal chances of above or below-average precipitation. In Tallahassee, the average max/min temperatures are 81.4/57.3, and the state capital receives 3.23 inches of rain.

SHORT TERM [Friday Through Saturday].

The upper-level eastern CONUS trough will remain in place through Saturday. At the surface, high pressure will move east with flow across the Tri-State region gradually veering more easterly at the base of the ridge. Highs will remain in the middle to upper 70s each day, with lows ranging from near 50 degrees in SE AL up to the upper 50s in the SE Big Bend on Saturday morning. No rain is expected.

LONG TERM [Saturday Night Through Thursday].

The superpositioning of shortwaves over the Midwest will result in a more progressive northern stream pattern as the consolidated wave advects ENE and pulls the eastern CONUS trough out of the Southeast. As the trough lifts north, the subtropical ridge will ease back into the W. Atlantic/Florida/E. Gulf region resulting in low/mid tropospheric flow veering more southerly. Meanwhile, a tropical wave is forecast to move into the western Caribbean and then possibly into the southern or western Gulf. As the wave enters the western Caribbean, another shortwave is forecast to move across the Midwest, but under the influence of the subtropical ridge, the core of the shortwave will remain well north of the Southeast. So, while convection is forecast to advect north from the tropical wave into the eastern Gulf (along with an old frontal boundary), the shortwave moving through the Midwest will amplify the longwave trough enough to push the subtropical ridge a bit further south, veering steering flow more westerly. This sets up low-level northeasterly flow and upper-level southwesterly flow that works against influences from either system reaching the local area. So, lying between these to areas of more active weather, we could see very little rainfall up until mid-week. The best chances for rain will be across the southeastern Big Bend and the immediate Panhandle coast. This pattern will remain highly dependent on the eventual size, intensity, and track of the tropical wave and should be considered a low- confidence forecast at this time.

AVIATION. [Through 12Z Friday]

Outside of VLD seeing borderline MVFR vsbys early this morning, VFR conds are ongoing at all terminals. Mostly clear skies and light northwest winds prevail thru today before a dry cold front moves across the area tonight. After frontal passage, winds shift out of the north/north-northwest AOB 10 kts for DHN/ECP/ABY in the 5-6Z timeframe, and TLH/VLD around 9Z.

MARINE.

Light winds and low seas are expected today, though a frontal passage later tonight will result in advisory level conditions once again. After tomorrow, borderline Cautionary conditions are forecast for the foreseeable future as winds remain elevated between a tropical wave to our south and high pressure to our north.

FIRE WEATHER.

Dry conditions prevail over the next few days, with light northwest transport winds and low dispersions across the Big Bend and portions of southwest GA. A cold front is forecast to sweep across the area Thurs night, increasing transport winds to around 10-15 kts out of the north to north-northwest. High dispersions mostly along the I-10 corridor are expected Fri afternoon. Overall, there are no fire weather concerns as min RH values will remain above critical thresholds.

HYDROLOGY.

Widespread or heavy rain is not forecast over the next several days. All area rivers remain below flood stage with a continued downward trend in river levels expected.

SPOTTER INFORMATION STATEMENT.

Spotter activation is not requested. However, spotters are always encouraged to safely report significant weather conditions when they occur (while following all local, state, and CDC guidelines) by calling the office or tweeting us @NWSTallahassee.
