.NEAR TERM [Through Thursday]... Dry conditions are forecast to continue through the overnight hours into Thursday morning as surface high pressure over the region slowly slides south over the Gulf. By afternoon, a cold front will slide south into central Mississippi and Alabama with large scale lift increasing under the right entrance region of the upper jet. This will help to spread scattered showers into SE Alabama and possibly SW Georgia by late afternoon. Low temperatures will generally be in the mid 40s to lower 50s tonight, with highs on Thursday ranging from the lower 60s in the north, to around 70 along and south of I-10.

.SHORT TERM [Thursday Night Through Friday Night]... With a surface Low pressure system centered north of the Great Lakes in Canada, the extended trough, although shallow, will be over the region Friday and the upper level ridge will be weakening. Another approaching surface Low, extending from Texas with a large plume of moisture is poised to provide rain on Friday for our AL and GA counties with Probability of Precipitation near 80-85 percent, with lower Probability of Precipitation across our FL counties. Winds will be light from the southeast, shifting west to north by term's end. With widespread rain in the AL and GA counties, the temperatures will remain cool with highs in the low 60s north of I-10 and upper 60s in the panhandle and Big Bend regions.

Long Term - Saturday Through Wednesday
An upper level ridge will build through the region after Friday's cold front passes. The ridge will translate east as a surface low approaches from the west by Monday night into Tuesday. Precip chances return for Monday night into Tuesday with the chance for showers and thunderstorms, although confidence in timing is low at this time. Both the GFS and ECMWF (European Centre for Medium-Range Weather Forecasts) agree with some instability over our CWA, yet severe weather is not anticipated at this time. A warming trend seems likely as we approach midweek with highs in the low 70s.

Marine
Light winds and low seas can be expected through Thursday. Winds and seas will show a modest increase Thursday evening through Sunday as a cold front approaches and passes through the local waters.

Fire Weather
Red flag conditions are not expected for the next several days.

Hydrology
Dry weather is expected through Thursday. A cold front approaches Thursday evening with the potential to drop around 1/4 inch of rain south of I-10 and up to an inch in SE Alabama and SW Georgia, mainly on Friday. Local rivers are steady or falling, thus we are not expecting any flooding concerns through the forecast period.
