Strong high pressure along the eastern seaboard will shift east into the Atlantic and extend back to the west-southwest across the southeastern States and the northern Florida peninsula through the remainder of the week. The high will support a moderate northeast to east wind flow over the Gulf waters through the period with nocturnal surges in the Cautionary range (15 to 20 knots) likely each night. Lighter winds will return to the waters during next weekend as the high weakens and the gradient relaxes.

...Warming Trend Expected The Remainder Of The Week... ...High Dispersions Expected On Tuesday And Wednesday...

Strong high pressure along the eastern seaboard will maintain pleasant dry weather with mainly clear nigheights and mostly sunny days through mid week as it slowly moves east-southeast into the Atlantic. During late in the week and into next weekend upper level ridging will build in over the Gulf and Florida in response to an amplifying upper level trough/closed low over the southwestern U.S. as attendant surface high pressure sets up shop from the Atlantic and extends west-southwest across the southeastern States and north Florida. Pleasant dry weather will continue through the period with a slow increase in moisture and warming temperatures expected each day under a low level east- southeast wind flow. Slightly below normal temperatures through Tuesday will moderate to near normal during mid week, then climb to above normal late in the week and into next weekend. Overnight lows in the 40s and 50s tonight and again Tuesday night will moderate into the 50s and 60s through the rest of the week, while daytime highs initially in the 70s warm into the 80s with some mid to upper 80s possible by next weekend.

Marine
Strong high pressure along the eastern seaboard will shift east into the Atlantic and extend back to the west-southwest across the southeastern States and the northern Florida peninsula through the remainder of the week. The high will support a moderate northeast wind flow over the Gulf waters tonight then becoming easterly the remainder of the period with nocturnal surges in the Cautionary range (15 to 20 knots) likely each night. Lighter winds will return to the waters during next weekend as the high weakens and the gradient relaxes.

Fire Weather
Some critically low humidity values below 35 percent will be possible across Levy county the remainder of the afternoon, but with low ERC values and sustained winds less than 15 mph no Red Flag conditions are expected. Moderate 20 foot winds and transport winds combined with mixing heigheights in the 4-5kft range will support high dispersion indices the remainder of today and again on Tuesday and Wednesday. A slow increase in moisture along with moderating temperatures is forecast mid to late in the week with no other fire weather hazards expected at this time.
