NWS Tallahassee, FL wrote its last area forecast discussion before the first event at Sep 3, 2:16 PM EST, 1 hour 54 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 316 PM EDT Mon Sep 3 2012 .NEAR TERM [Through Tonight]... With the presence of the upper level trough digging into the region, areas of convection may linger into the overnight hours longer than is typical for this time of year. The highest rain chance during the overnight hours is expected to be in southeast Alabama and portions of southwest Georgia closest to the influence of the upper level trough. In fact, the model consensus suggests likely PoPs in that region for the overnight hours and the official forecast follows suit. Our local 12z hi-res ARW run (12z RAP initialized with 12z NAM boundary conditions) is somewhat concerning and indicates that an area of training convection could develop during the overnight hours across portions of southeast Alabama and adjacent sections of southwest Georgia. The large scale environment could support such an occurrence with precipitable water values forecast around 2.25 inches and relatively weak steering flow. This is something that we will need to keep a close eye on through the evening hours. A mention of heavy rain was added into the forecast for late tonight across southeast Alabama and adjacent areas of southwest Georgia. Hopefully our local 18z hi-res ARW run (18z RAP initialized with 12z GFS boundary conditions) will shed some additional light on this potential scenario. Min temperatures in the low to mid 70s are expected areawide. && .SHORT TERM [Tuesday Through Wednesday Night]... The unsettled weather pattern which begins tonight, will continue right through Wednesday night. A weak trough (loosely associated with the remnamts of Isaac) is forecast to slide south across the region over the next several days, with a weak surface low possibly developing over the northeastern Gulf by Wednesday. With copious amounts of moisture available (PWAT 2-2.5 inches) along with modest upper forcing, expect solid coverage of convection each day. The guidance is in good agreement in showing the development of multiple convective complexes over the the next 60 hours. However, the exact timing, intensity, and location of these episodes remains highly uncertain. Given the generally weak flow aloft, severe weather is not the primary threat. However, there may be a risk for localized flooding given the tropical nature of the airmass. Some of the CAMS guidance is showing isolated rainfall totals of 5-10 inches over the next 48 to 60 hours. Will continue to monitor the evolution of this system, and a Flash Flood Watch may need to be considered later if the convective trends indicated by the hi-res guidance bear out. Have bumped up PoPs through Wednesday night from previous forecast, with likely PoPs for much of the area Tuesday and Wednesday afternoons. Kept southeastern Big Bend a bit drier since it will be closer to the subsident region on the west side of a TUTT low over central/south Florida. && .LONG TERM [Thursday through next Monday]... Rain chances will continue each day with possibly the best chance late next weekend as models show a very deep trough over the eastern CONUS with an upper low closing off over the Ohio Valley. This will send a strong cold front into the southeastern U.S. over the weekend with a frontal passage possibly by the end of the forecast period. Would like to see more run to run consistency before increasing PoPs higher than chance and dropping temps and dew points too low for the start of next week. && .AVIATION [Beginning 18Z Monday]... As an upper level trough affects the region, areas of convection may linger into the overnight hours with the highest chance around KDHN and KABY. Some MVFR to IFR cigs may also affect the terminals towards dawn on Tuesday. && .MARINE... Relatively light southwesterly flow will continue through Tuesday morning. However, by Tuesday afternoon and evening, the gradient is forecast to tighten as weak low pressure drops south towards the Gulf Coast. Exercise caution conditions are possible by Wednesday morning over the western waters, speading eastward by Wednesday afternoon. A period of advisory conditions is not out of the question at some point on Wednesday or Thursday. Winds and seas should diminish by late in the week as the trough of low pressure moves east into the Atlantic. && .FIRE WEATHER... Relative humidity values will remain safely away from critical levels for the next several days. Thus, no fire weather hazards are currently anticipated. && .TAE WATCHES/WARNINGS/ADVISORIES...
