870 FXUS62 KTAE 230136 AFDTAE AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 936 PM EDT Wed Oct 22 2014 .Near Term [Through Tonight]... Despite the continuation of the cool air advection, the projected positioning of the Sfc ridge overnight no longer appears ideal for radiational cooling. Therefore, split the difference on overnight low temps with the previous package and the latest local CAM run which essentially raises minimum temps about 3-4 degrees across the board. Tomorrow night, on the other hand, should be more favorable for radiational cooling with the ridge building in closer to overhead. && .Aviation... [Through 00Z Friday] More of the same with the Taf sites, as VFR conditions with clear skies and light winds will continue to persist for at least the next 24 hrs at all of the terminals. && .Prev Discussion [334 PM EDT]... .Short Term [Thursday Through Friday Night]... As the large upper low lifts northeastward, it will be replaced by a short wave trough moving through the Great Plains. This trough axis will then sweep east of the area Friday night. The surface high centered over the Great Lakes will slide steadily southward to a position over the Northwest Gulf Coast by 12Z Saturday. This pattern will maintain the dry weather we have enjoyed for a week now. We will see cooler than normal conditions through most of this period, although Friday`s highs will be pretty close to seasonal averages. Thursday`s highs will run about 4 degrees below normal with mid 70s north to upper 70s south. Low temps will be back down into the lower 40s for most inland areas Thursday night and modify slightly to the mid to upper 40s for Friday night. .Long Term [Saturday Through Wednesday]... As the trough exits east of the area, the flow across the CONUS will become more zonal. Some weak upper ridging will work eastward across the Gulf Coast and FL through the period with the next long wave trough just starting to deepen across the Plains on Wednesday. This means temps will warm once again with 80s for highs and 50s for lows. It will remain dry with slight chance PoPs only working their way back into the forecast by Tuesday night and Wednesday. It should be noted that the 12Z ECMWF now takes the remnant of TD 9 from the northwest Caribbean Sea and lifts it northward into the Central Gulf of Mexico on Wednesday. The 06Z GFS was doing something similar with an even stronger system, but the latest version has backed off. Until we see some run-to-run consistency in the models, we will not give too much regard to this scenario. .Marine... Offshore flow will persist across the waters through much of the period. Wind speeds will increase to cautionary levels tonight, and may briefly approach advisory levels, before decreasing below headline criteria on Thursday. Moderate offshore flow will then persist into the weekend with winds weakening on Sunday and veering to the east by Monday. .Fire Weather... Very dry air will continue to filter into the region from a ridge of high pressure off to our northwest. Although conditions are expected to remain below Red Flag levels at this time, slightly longer durations of low relative humidities and slightly higher ERC values could put a small portion of the Florida Big Bend in Red Flag conditions. Therefore, the situation will be monitored closely over the next few days. .Hydrology... There are no hydrologic concerns across the region since it hasn`t rained in a week and no rain is expected for about another week. && .Preliminary Point Temps/PoPs...
