Short term (today and Tuesday)
Broad cyclonic flow extends from the northern plains to the
great lakes and into new england. South and west of this
feature, potent upper level ridging persists from the
southern rockies into northern mexico, bringing an extended
bout of extreme heat to parts of the southwestern u.S. A
remnant cold front has stalled across the central florida
peninsula in response to a number of shortwave troughs
moving through the cyclonic flow aloft. As these shortwaves
depart to the north and east, the front will remain stalled,
eventually becoming washed out over the next day or two.

Showers and storms got an early start today aided by
enhanced convergence due to the presence of the weak front
and seabreeze circulations. Greater coverage has so far been
confined to areas along and just south of the front from
tampa bay north and east toward orlando. As winds continue
to veer with the seabreeze passage, expect storms to migrate
inland through this evening. Much like last night, showers
and storms may linger well into tonight over interior
portions of the peninsula, eventually winding down around

For tomorrow expect much of the same. The weak front will
remain over the region, shifting a bit further south. This
will allow winds from tampa bay north to shift onshore
earlier, and may limit any rain chances to the late morning
and early afternoon hours. Convective coverage may be
enhance south of tampa bay in vicinity of the front and
interactions with seabreeze and frontal circulations. As
with today, storms will shift inland as westerly winds push
the west coast seabreeze inland.

Temperatures will remain near climatological normals with
highs ranging from the mid 80s along the coast to around 90
degrees elsewhere, and lows in the mid to upper 70s.

Mid term long term (Tuesday night-Monday)
Weak mid upper level ridging will remain across the area
through the period. Meanwhile at the surface a stalled out
front across north florida at the start of the period will
dissipate with high pressure moving across the eastern u.S.

Wednesday. During Thursday through next Monday the high will
move well out into the atlantic ocean with the ridge axis
setting up to our north. This will lead to a typical
summertime low level east to southeast flow across the
region and when combined with the sea breezes and abundant
moisture will lead to scattered to numerous diurnal showers
and thunderstorms each day drifting west out into the gulf
at night. Temperatures will remain seasonable with daytime
highs mostly in the upper 80s to lower 90s and overnight
lows in the 70s.

Aviation (18z tafs)
Scattered to numerous showers and storms have erupted early
today along and near a weak frontal boundary from tampa bay
northeast to orlando. This activity will gradually work its
way eastward with additional storms developing along the
seabreeze along the southwest florida coast through the
afternoon. With this evolution, most any terminal may see
visibility and ceiling limitations due to storms and will
maintain vcts. Storms should move east of coastal terminals
by 21z to 22z but may linger over interior areas into this
evening. Visibilities less than 1 2 mile and gusty winds
will be common with any thunderstorms.

High pressure will remain fixed over the waters through
this week and into the weekend, maintaining light winds and
favorable seas. The seabreeze will turn winds onshore each
afternoon near the coast. The only marine hazard will be
widely scattered marine thunderstorms, which may locally
enhance winds and seas, and produce heavy rainfall and
frequent lightning.

Fire weather
With abundant moisture in place and daily rain chances,
humidities will remain well above critical levels.

Therefore, no fire weather concerns are expected over the
next week.

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 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.
