549 FXUS62 KTAE 271354 AFDTAE AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 954 AM EDT Wed Aug 27 2014 .Near Term [Through Today]...
-- Changed Discussion --
Surface high pressure along the eastern seaboard will continue to weaken and slide south today as a ridge of high pressure builds aloft over the southeastern states. With light northeasterly flow, high pressure aloft, and meager deep layer moisture (12Z KTAE PWAT 1.2 inches), no precip is expected today for land areas. Temperatures will be warm with highs reaching the mid 90s for most areas. No changes were needed to the forecast grids this morning.

.Short Term [Thursday Through Friday]... The upper ridge with very dry air in the mid to upper levels will start to gradually break down during the short term. The low level flow which will be from the east to northeast today will gradually veer to the south by Friday and bring a gradual increase in moisture to the boundary layer. However, PoPs will generally remain below 20% over land until Friday as we have a ways to go to moisten the airmass back up again. By Friday, it appears as though sufficient moistening will have occurred to allow for a return to scattered afternoon convection. Temperatures will be rather warm through the period with mid 90s common, but with the dry air in place, heat indices will not be much higher than that on Thursday with a slight uptick on Friday as moisture increases. .Long Term [Friday Night Through Wednesday]... The GFS and ECMWF show the Tri-State region residing on the western periphery of deep layer ridging through Saturday. After that the GFS expands the ridge westward while becoming less amplified. The ECMWF keeps the area under the western portion of the de-amplifying ridge. At the surface, low level flow will be southerly with the high situated well east of the Atlantic seaboard. Both solutions show a return of deep layer moisture to the area with near to above normal rain chances each day. Despite the increase in rain chances, max temps will generally be above climo in the lower to mid 90s. .Marine... Caution level easterly winds will gradually diminish through the morning hours with winds expected to drop below caution levels by late morning. Lighter winds and seas are then expected to prevail through the weekend with winds gradually veering to onshore. .Fire Weather... A dry air mass is expected to push into the area over the next couple days. Winds are not expected to be sufficient for red flag conditions, but the afternoon relative humidity should be quite low for this time of year. .Hydrology... There are no hydrological concerns at the present time with little to rain expected for the couple of days. Scattered convection is expected to return for Friday into the weekend, but flooding is not expected at this time.
