Area forecast discussion, Aug 20, 2:29 PM CDT, 2 hours before
Area Forecast Discussion National Weather Service Tallahassee FL 329 PM EDT SAT AUG 20 2016 .NEAR TERM [Through Tonight]... Local radar imagery shows scattered showers and thunderstorms developing across southeast AL and the FL Panhandle this afternoon. Further development across eastern portions of our area is expected as the day goes on, but most of the coverage will stay in the western and northern parts of our forecast area this afternoon and evening. Overnight minimum temperatures will hover around the mid 70s, upper 70s along the immediate coastline. .SHORT TERM [Sunday Through Monday Night]... Mid level trough extending from the Great Lakes southwestward to the southern Plains will generally move eastward through the short term period and support a weak cold front as it moves southeastward. The front will remain north of the CWA Sunday and thus the best low level convergence will reside north as well. PWATs remain around 1.8 inches through much of the area with a slight bump to 2 inches across southeast Alabama and have tapered higher PoPs in that direction. By Monday, mid level high pressure slides underneath the mid level trough across the Gulf of Mexico and effectively stalls the surface cold front near the I-10 corridor. PWATs up to 2 inches and low level convergence across the central and southern portions of the CWA will warrant a good chances for storms Monday afternoon. High temperatures each day will reach the lower to mid 90s. If clouds are more abundant Monday, high temperatures may be a little lower than forecast. .LONG TERM [Tuesday Through Saturday]... Mid level high reasserts itself across the southern and southeast CONUS at the beginning of the long term. Weak cold front will dissipate Tuesday with surface high pressure near the mouth of the Mississippi controlling the surface flow with weak northerly flow. Surface high pressure ridge sliding down the Appalachians will cause winds to become more easterly Wednesday and Thursday. An inverted trough moving towards the lower Atlantic coast will cause winds to back to the northeast towards the weekend. Diurnal convection will continue through the period. Highs will be in the lower to mid 90s each day. && .AVIATION [Through 18Z Sunday]... Storms have already begun to pop up, but are widely scattered and may not directly affect our local TAF sites. These storms are not expected to linger very long into the overnight hours. Brief MVFR ceilings may be possible once again tomorrow morning near DHN and ABY, but confidence was too low to put in this TAF package. && .MARINE... High pressure will remain across the northern Gulf of Mexico coastal waters through the upcoming week. Winds will generally remain below 15 knots and seas will be 2 feet or less. Isolated to scattered showers and thunderstorms can be expected through the period. && .FIRE WEATHER... Hazardous fire weather conditions are not expected over the next several days. && .HYDROLOGY... Scattered afternoon showers and thunderstorms will continue. However, there are no widespread flooding concerns. && .PRELIMINARY POINT TEMPS/POPS...
