Short term (today and Wednesday)
A potent upper cutoff low has moved little over the last 24
hours, remaining over west central tennessee and kentucky.

This feature, combined with several weak areas of surface
low pressure, have led to unsettled weather across the
southeast u.S. Over the last few days. A surface low is
shifting eastward this morning across georgia and northern
florida. As this feature finally lifts northeastward, a
quieter weather pattern looks to set in.

This morning, ongoing showers and a few storms offshore
will persist along ahead of the cold front as it gradually
moves southward. While some instability exists over the warm
waters, only showers are expected inland through the
morning hours. This will change late morning into the
afternoon as instability increases due to daytime heating.

Frontal convection will likely decrease through sunrise and
perhaps a few hours after, but redevelop with insolation and
increasing instability. Areas of interior south florida
appear to have the highest probability of showers and storms
during the early to mid afternoon hours. Heavy rain, gusty
winds, and frequent lightning will accompany any stronger
storms. Elsewhere, a progressively drier more stable airmass
will advect into northern and central florida, with partly
cloudy skies and slightly cooler afternoon highs.

Tonight, with slightly drier air in place and light winds,
expect lows will be pleasantly cool in the upper 50s to low
60s many areas. Despite drier air moving in and light winds,
some patchy fog will remain possible across mainly interior
low lying areas where shallow moisture remains.

Wednesday looks to be very pleasant, with highs ranging
from the upper 70s north to the lower 80s elsewhere. The
lower humidity will make for a very pleasant day with light
west northwest breeze and mostly sunny skies. This is about
as good as it gets toward the end of april.

Mid long term (Wednesday night through Monday)
Rather quiet weather expected in the mid long term forecast
period. A few shortwaves will move through the base of an
upper- level trough in place across the eastern CONUS on
Thursday and again on Saturday. Although lift will be
enhanced somewhat, moisture looks to remain fairly limited
so pops will be 20 percent or less across the area. Upper-
level ridging then looks to build over the area during the
weekend with surface high pressure becoming centered across
the mid- atlantic states by early next week. Mostly sunny
skies are expected each day with highs in the lower to mid
80s with lows in the upper 50s to upper 60s into Saturday.

Beginning Sunday and continuing into next week, as h5
heights rise, temps will be a few degrees warmer with highs
pushing into mid to upper 80s regionwide.

Aviation (06z tafs)
Prevailing MVFR ifr ceilings expected through around 14z
ahead of a weak front. Shra tsra possible along and ahead of
the front from ksrq south to kpgd kfmy krsw. Winds will
remain west southwest, shifting to the northwest after 00z.

A cold front will move across the waters through the day
today, bringing a chance of showers and storms to the
central and southern waters through early afternoon. Drier
air will move in behind the front with breezy northwest
winds as high pressure builds in over the region. Another
weak front may approach the waters late in the week into the
weekend. Winds generally look to remain west to northwest
10 to 15 knots or less with seas 3 feet or less through the

Fire weather
A cold front will move through the area today, bringing in
drier and slightly cooler air through the remainder of the
week. This will result in humidities of 35 to 40 percent
each afternoon, but winds look to remain low enough to
prevent any fire weather concerns.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
