257 pm edt Mon apr 23 2018

Short term (rest of today and Tuesday)
Aloft - a broad low over the mid-mississippi valley early this
afternoon meanders into the central appalachian chain... Troughing
southward with an axis initially over the gulf of mexico that eases
toward fl. Surface - a surface reflection of the upper low has a cold
front that arcs southeast across the eastern gulf coastal states
then south and southwest over the gulf. As the upper low slips
east the front slides across north fl late tonight then through
southern fl by late Tue afternoon.

A band of deeper moisture... Model pwat ranges from 1.6 to 1.8
inches... Across ne-central fl and southwest over the gulf continues
to push east this afternoon then begins to erode away tonight and
shifts into east-central and southwest fl by Tue afternoon.

Scattered showers are lined up over our inland counties and are
moving to the east and northeast. The greatest coverage this
afternoon is expected to mainly stay east although can not rule
out a few showers or storms popping through the evening across
coastal locations. The front will support a band of isolated-
scattered showers moving across central fl overnight then through
the southwest sections Tue morning and afternoon... With enough
lift for a few thunderstorms in the afternoon.

Mid term long term (Tuesday night through Monday)
Upper troughiness to hold over the eastern u.S. With series of
lows shortwaves spinning and rotating through the overall flow
mainly well north of the local area through mid week with dry air
aloft. High pressure builds into the region with dry and pleasant
slightly below normal temps.

Later in the week, upper shortwaves to deepen longwave trough into
the gulf coast region dragging several weak surface features through
the region into the weekend. Mean layer moisture looks to remain
fairly limited so will keep pops only in the slight chance category
thu-sat. Brief and weak upper ridging begins and drier high pressure
at the surface to build into the region Sun mon. Temps expected to
run with a few degrees of climate normals over the weekend and into
early next week.

Aviation
23 18z tafs. BknVFR CIGS into the late evening then becoming MVFR
cigs til aft sunrise... But with LCL ifr CIGS late night and toward
sunrise. Both lal pgd could see some MVFR br near dawn. Have opted
to pull vcnty shra tsra expect for the south which may see isold
shra later this afternoon. SW winds with a few gusts possible this
afternoon... Diminish over night... Then increase in the morning and
shift to westerly.

Marine
High pressure will be broken up of by a couple of weak fronts
moving through during the rest of the week. Winds and seas
generally benign although locally higher near and in isolated
thunderstorms.

Fire weather
Abundant moisture with showers and storms will preclude any low
rh concerns. Robust transport winds Tue will create locally high
dispersion values.

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.
