Update
For 06z aviation.

Short term
Through tonight.

Tight surface pressure gradients have allowed some gusty winds
for this afternoon as we transition with our exiting low pressure
system toward new england and building high pressure from the gulf
of mexico. Winds are expected to relax tonight as surface ridging
takes over with mostly clear skies, light to near calm winds and
and a dry atmosphere. Look for one more pleasant and cool night
tonight before the atmosphere begins rebound and moderate back as
southwest flow the heat returns as we head into the weekend.

Long term
Friday through Thursday.

Warmer temperatures return on Friday as upper level ridging builds
in across the area. The ridge begins to flatten as we go into
Saturday and a surface low moves through the ozarks and into the
ohio river valley. The system is under generally zonal flow and
doesn't feature much in the way of moisture return. The GFS keeps
any precip north of the area, while the ECMWF has the front edging
into our northern counties before stalling and providing just enough
lift for some thunderstorm activity. Have kept mention for a chance
of thunderstorms in the forecast for Saturday night into Sunday for
much of the north half of central al.

On Sunday, an upper low moves into the upper midwest as a trough
digs through the central plains. This low will stretch a cold front
down through the mississippi river and ohio river valleys. Sunday
evening, the GFS shows much higher instability and lower shear,
while the ECMWF shows lower instability with 40-45kt 0-6km bulk
shear magnitudes. Will leave out any mention of severe in the
forecast given the differences in the models, but will continue to
monitor the trends in coming days.

The cold front will push through central al late Sunday night and
into memorial day leading to widespread rain. Have bumped up the
pops for Monday to account for the latest trends in guidance. Even
with modest instability for this time of year, the upper level jet
remains well to the north of the area, so shear values are on the
lower end. Therefore, current thinking is that any thunderstorms on
Monday will remain below severe limits, though we could see some
isolated storms on the stronger side.

The front slowly pushes southeastward by Tuesday morning. Models
hint that the front stalls around this time as zonal flow returns
aloft. The ECMWF pushes it a little further south than the GFS does,
but either way, the lift along the front could spark a few
thunderstorms Tuesday and Wednesday as well, especially during peak
heating. Have gone with lower-end chance pops for the southern
counties towards middle of next week to account for any shower storm
activity along the stalled frontal boundary.

Vfr conds thru the period. Calm winds overnight will become
southwest 5-8 knots by 15z.

Rain free conditions and lower humidity values will prevail
through Friday and for most on Saturday. Significant rain chances
hold off until Sunday when the next upper level system and surface
front approach. Critical fire weather conditions are not
expected.

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.
