synopsis...

latest surface analysis showed a deep 992mb low over ny nj with a
trailing cold front south southwest to georgia to east central
mississippi. A 1022mb high was located eastern oklahoma and
arkansas pressure gradient relaxed with a mb change from the high
to our forecast area. Upper air analysis showed the main trough
axis slightly negatively tilted from hudson bay to the mid
atlantic states and northwest flow over mississippi valley this
morning. In addition, a cyclonic circulation was located over
utah.

Discussion...

upper level trough will remain on the east coast. However, the
system over utah will move west over the central plains late
Friday. The approaching system will increase heights over the
mississippi valley Friday and Saturday. While not a true ridge
ahead of this system, the slight warming trend will continue with
afternoon temperatures for today and Saturday about 5 degrees
warmer than yesterday. All in all, weather will remain dry and
spring like through the weekend.

The system will push east Sunday through Monday. Several
disturbances will provide a push southeast from southern arkansas
to northeast gulf on Monday. Surface base CAPE values of 800 to
1000 j kg will be available but positively tilted trough axis will
yield 0-3km helicity 100 m S midday Monday. Will maintain
isolated TS with generally scattered showers. Rain threat will
push south Monday night with drying Tuesday behind the cold front.

Slight cold air advection will knock down temps back to near
normal for late march.

Aviation Vfr conditions will prevail for the forecast period for
all terminals. -bl

Marine High pressure currently in place will move eastward
tomorrow afternoon. Winds will generally be light but the winds
will shift to onshore flow Saturday as the high pressure moves away.

The next real chance of rain and stronger winds will be on Monday as
a cold front moves through the area. -bl

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.
