.NEAR TERM [Through Tuesday]... Scattered showers and thunderstorms along a low-level convergence zone near the AL/GA border will continue to be a focus for storm development through the remainder of the day. Additional storms are possible in the FL Panhandle along the seabreeze, but expect coverage in these zones to be more isolated due to lesser levels of convergence at the surface. One last area of showers and storms is possible in extreme eastern zones along and northeast of the I-75 corridor as outer rain bands from Tropical Storm Isaias rotate through. Outside of any showers, expect very warm temperatures in the mid to upper 90s.

For Tuesday, the base of the upper level trough will rotate through the area and advect deep layer dry air into the region from the northwest. Precipitable water content will drop from 1.75-2.00 inches to around 1.25-1.50 inches on Tuesday. This will discourage shower and thunderstorm development but we'll have to keep an eye on any isolated storms that develop as the drier aloft could lead to slightly stronger wind gusts in any thunderstorms. Hot temperatures are expected to continue with high temperatures climbing into the mid to upper 90s again.

.SHORT TERM [Tuesday night through Wednesday Night]... A broad upper trough remains over the eastern half of the country Tuesday night with whatever is left of Isaias all the way into the northeast by this time. Winds aloft turn more southwesterly on Wednesday with a cold front moving into our SE AL counties. However, with the drying NW flow and with the trough pulling back to the north, the front will stall and rain chances remain around 30% or less. Highs will be in the mid to upper 90s with lows in the lower 70s.

Long Term - Wednesday Night Through Monday
Mid level ridging builds in from the east starting on Thursday which will help keep the front stalled near the region. With winds so light, the highest probability of precipitation for Thu-Fri will be in the east, where the east coast sea breeze will move in. By Saturday, weak shortwaves will move through aloft combining with a convergence boundary at the surface leftover from the stalled front. By Sunday, we see our highest probability of precipitation for the week as moisture increases which will allow more widespread showers and storms. High POPs remain in the forecast for Monday afternoon as well. Highs in the long term will be in the mid 90s with lows in the mid 70s. Heat index values will be 100-105 with a few spots higher than that every now and then.

Marine
West southwest winds less than 10 knots will prevail through the work week with seas less than 2 feet. Isolated to scattered showers and thunderstorms return to the forecast mid week.

Fire Weather
Red flag conditions are not expected the next few days but dispersions will be on the higher side on Tuesday and possibly into Wednesday

Hydrology
Less than one inch of basin averaged rainfall is forecast through the next 7 days so therefore, there are no significant flooding concerns for the next several days.
