Today: Mostly sunny, with a high near 87. Calm wind becoming west between 4 and 7 mph. 

Tonight:Partly cloudy, with a low around 56. West wind between 4 and 7 mph becoming calm. 


Hazardous weather: during the nighttime hours, Patchy fog is expected to develop with isolated areas falling to below a mile visibility.


Forecast Details: latest MSAS analysis shows high pressure has settled south and now resides from the eastern Gulf through the Florida Peninsula and into the Atlantic. This has provided for a light flow regime at the surface. Aloft however, RUC analysis shows conditions are not quite as conducive as previous night for fog formation with a quick moving zonal flow in place. Still expect some reductions to visibility with dew points now in the 60s, but may need to scale back some of the patchy dense from the initialized grids. Also seeing some developing southerly flow between 850mb and 700mb which has resulted in a surprisingly dense cloud deck over the Florida interior. Cross sections show this zone of southerlies to be fleeting and should scattered out by midmorning.

For the remainder of today, expect mostly sunny to partly cloudy conditions and continued warm with temperatures approaching 90 for the interior. Shortwave approaching the lower Mississippi Valley tonight will act to enhance 850mb-700mb ridge and should see a little more in the way of fog inland. 

Today's Pollen Levels: 6.4 Medium (on a scale to 12); Predominate Pollen: Ragweed, Grass and Chenopods.
