Area Forecast Discussion National Weather Service Tallahassee FL 356 AM EDT Thu Jul 29 2021

. DANGEROUS HEAT THROUGH THE WEEKEND .

NEAR TERM [Through Tonight].

Today begins a multi-day stretch of dangerous heat indices as upper ridging centered across the middle part of the country extends eastward into the southeast states. This extra ridging is expected to result in less convective coverage overall and higher temperatures. The best chance of thunderstorms today is expected to be confined closer to the coast and offshore with only low chances further inland across southeast Alabama and southwest Georgia. Meanwhile, low level moisture will remain plentiful, and the combination of high temperatures and high dewpoints is expected to drive heat index values to near 108 this afternoon across a large portion of the area. Thus, a heat advisory remains in effect for most of the area today. Not much relief is expected tonight with muggy overnight lows in the mid to upper 70s, which will set up an even hotter days on Friday and Saturday.

SHORT TERM [Friday Through Saturday].

Dangerous heat conditions will be the focal point of the short- term as the axis of a strong ridge noses in further from the northwest, thus keeping rain chances below seasonal percentages. This setup should prompt high temperatures to soar into the upper 90s (isolated 100 possible) away from the coast, while lows uncomfortably drop to the mid-upper 70s. The relative humidity is going to drive daytime heat indices well into advisory levels (108-112 degrees), with some locations meeting excessive heat criteria (>=113 degrees).Therefore, an Excessive Heat Watch has been issued for the FL Panhandle on Friday, and another (more widespread) Watch is anticipated for Saturday. These feel-like temperatures cause heat-related illnesses and symptoms, so taking the proper actions is essential - hydrating, staying cool, wearing light-colored clothing, etc. Heat safety tips and resources can be found in the following link: www.weather.gov/safety/heat.

LONG TERM [Saturday Night Through Thursday].

Hot weather continues on Sunday, albeit slightly less pronounced than Saturday (highs in the low-mid 90s), but daytime heat indices stay within advisory range. Although near-seasonal rain chances (45- 60%) may provide some reprieve, convective coverage is expected to be isolated to scattered. The ridge responsible for the dangerous heat weakens by Monday in response to a broad upper trough swinging across the region, thus putting a merciful end to the hot streak. We then transition to a wet, unsettled pattern as an attendant frontal boundary approaches from the north and provides a focus for scattered to numerous showers and thunderstorms, along with the seabreeze, and plentiful upper- support. The rainfall forecast is justifiably in the likely to definite category areawide for the remainder of the period thanks to troughing remaining in place. The environmental factors should also allow convection to be strong to perhaps marginally severe and persist longer than usual after sunset. Stronger storms will pose a heavy rain, frequent lightning, and downburst threat. The widespread precipitation and cloud cover is expected to keep high temperatures mainly below 90 degrees, with lows in the 70s.

AVIATION. [Through 06Z Friday]

Some brief patchy fog or low clouds are possible early this morning, otherwise VFR conditions are expected to prevail. The best chance of thunderstorms later today is expected to be near ECP and TLH with only low chances farther north.

MARINE.

The main boating concerns over the next few days are thunderstorms. Today looks stormy, with maritime convection already apparent as of 245am ET. Expect coverage to increase through the morning and into the afternoon. Some storms may be strong, capable of producing frequent lightning and winds hazardous to vessels. A stray waterspout cannot be ruled out either. Otherwise, west to southwest winds at 15 knots or less prevail through the weekend, before cautionary conditions arrive by Sunday night.

FIRE WEATHER.

There are minimal fire weather concerns expected for the next several days outside of occasional low dispersions.

HYDROLOGY.

Lower than normal precipitation is forecast through the weekend before a wetter pattern takes place early next week. Widespread rainfall amounts are 1-2" (isolated 3"+), mainly from Monday to Thursday. Flooding may be a concern during that timeframe. Several rivers in Ochlockonee and Suwannee basins remain in action stage, but are cresting/falling, except Rock Bluff, Wilcox, and Manatee Springs, where rises are forecast.

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.
