511 FXUS62 KTAE 230653 AFDTAE AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 253 AM EDT Thu Oct 23 2014 .Near Term [Through Today]...
-- Changed Discussion --
Seasonable temperatures and dry conditions are on tap for today as the region remains situated between high pressure to the north, a nor`easter off the New England coast, and lower pressure over the southern Gulf and northwestern Caribbean. .Short Term [Tonight Through Saturday]... A northern stream shortwave currently over the Northern Plains will dive into and through the Southeast Friday through Saturday. With a large pool of dry air sprawling across the eastern third of the country through the central Gulf, and a very progressive wave, there won`t be nearly enough return flow to supply any deep layer moisture to the system as it moves into our region. Further, low-level flow will remain northerly around high pressure which will hardly be affected by the passing shortwave. In short, Friday and Saturday will remain dry with highs near seasonal averages, and lows around 10 degrees below average. .Long Term [Saturday Night Through Thursday]... 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.
