Scattered showers and thunderstorms will continue to move
north through the area overnight, causing periods of
MVFR-ifr conditions. Widespread MVFR ceilings will spread
across the area overnight as a cold front passes south through
the area. On Thursday, periods of MVFR ceilings will
continue throughout much of the day under breezy northwest
winds.

Turning much cooler and drier on Friday and into the
weekend...

short term (tonight - Thursday)...

an amplified upper air pattern will persist across the conus
during the short term period. An upper level trough closed
low over the lower mississippi valley this afternoon will
lift northeast into the ohio valley through Thursday. At the
surface an area of low pressure will develop along a
stalled frontal boundary over the eastern gulf tonight. This
low will then deepen as it lifts out to the northeast up
along the mid atlantic coast through Thursday. As the low
lifts out a trailing cold front will sweep southeast through
the forecast area later tonight and early on Thursday.

Ample moisture and lift will support scattered to numerous
showers and isolated storms across the forecast area tonight
through early Thursday as the front moves across the
region.

On Thursday any lingering rain during the morning will end
by early afternoon as much cooler and drier air advects
into the region on an increasing northwest to northerly wind
flow in the wake of the front. Temperatures will be mild
through the first half of tonight, then cooler drier air
will begin to move in from the north early on Thursday, and
highs temperatures on Thursday will likely occur during the
morning hours with steady or even falling temperatures
possible during the afternoon as strong cold air advection
gets underway. Low temperatures tonight will range from the
lower 60s north, mid to upper 60s central, and around 70
across southwest florida with highs on Thursday in the mid
to upper 60s north, around 70 to the lower 70s central, and
mid 70s south.

Long term (Thursday night - Wednesday)...

by Thursday night, the surface front will have pushed south
of the area, with the moisture lingering behind the front
across the southern half of the area and some of the cooler
drier air starting to push into the nature coast. The upper
low will be in place to the north of the area and lift out
to the northeast through Friday. The clearing behind the
surface front continues to push south through Friday, with
the cooler and drier air overspreading the area as high
pressure builds into the southeast u.S. Lows Thursday and
Friday night in the upper 30s to lower 40s north and in the
mid 40s to mid 50s elsewhere. Highs Friday mid 60s to lower
70s, then lower to mid 70s Saturday afternoon.

Surface ridging then continues across the area through the
weekend as conditions moderate, and aloft generally W sw
flow remains across the area. A weak front then moves into
the area Monday night, with upper energy lingering across
the area through the end of the period. No appreciable rain
chances expected with this however. Highs will linger in the
70s to around 80 through the rest of the period, with lows
in the 50s to lower 60s.

Marine... Developing low pressure over the eastern gulf
along a stalled frontal boundary will deepen as it lifts out
to the northeast across the northern peninsula later
tonight and then up along the mid atlantic coast through
Thursday night. As the low lifts out to the northeast a
trailing cold front will get pulled southeast through the
waters later tonight through early Thursday with winds
shifting into the northwest and north in its wake with a
period of small craft conditions likely with hazardous
boating conditions developing. With wind and seas expected
to increase overnight into Thursday in the wake of the front
will hoist small craft headlines for the offshore waters
for later tonight through Thursday, with cautionary
headlines closer to shore. The building seas and increasing
onshore flow will also increase the potential for dangerous
rip currents at all area beaches later tonight through
Thursday night and will hoist a high risk of rip current
statement as well. Lighter winds and lower seas will return
to the waters on Friday night and into the upcoming weekend
as surface high pressure builds in over the gulf in the wake
of the front.

Fire weather...

much cooler and drier air in the wake of a cold front will
move into the region to close out the week. Humidity
values may fall close to 35 percent over interior locations
during Friday afternoon, however low erc values and
diminishing winds will preclude red flag conditions. A slow
increase in moisture is expected during the weekend as winds
quickly veer into the northeast and east with no other fire
weather hazards or concerns expected.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
