Synopsis
Warmer conditions are expected today before a frontal system brings
rain and increased winds to the region later tonight and Tuesday.

Near- average temperature and dry conditions are then expected the
remainder of the week.

Near term until 6 am this morning
Shortwave ridging in the wake of the exiting nestor will maintain
dry weather and seasonably warm conditions for tonight. Light wind
with areas of clear sky will support patchy, shallow fog as crossover
temperature will likely be achieved.

Short term 6 am this morning through Wednesday night
A deepening, closed upper low will advance toward the upper ms
valley, promoting strong sly flow over the ohio valley. Despite
increasing cloud cover, warm advection will enable daytime high
temperature to reach 10-15 degrees above average.

Rain coverage should expand from west to east later tonight as the
boundary layer saturates with increasing low level jet support ahead
of an encroaching cold front. Strong forcing for ascent of
precipitable water in excess of 1.40" (+ 90% climatological average)
should support periods of moderate rainfall through Tuesday morning
as the cold front quickly advances through the forecast area.

Subsiding air in building high pressure will support a drying trend
Tuesday behind the cold front. Lingering low level moisture should
fuel the development of a cumulus deck under broad upper troughing
tues afternoon, with strong wind mixing to the surface via steep
low-level lapse rates and a decent gradient wind.

Cold advection behind the front will return daytime high temperature
to near average values. Similarly, as dry air and clearing sky ensue
tue night in the wake of the upper wave, minima will also end up
near seasonal average.

Quasizonal flow aloft and surface high pressure should support a dry
and seasonably cool wed.

Long term Thursday through Sunday
Although long range models diverge on details, the consensus
suggests return flow ahead of a deepening plains trough, supporting
at least seasonable temperature in the long term. Precipitation
chances will be dictated by shortwave activity in swly flow aloft
ahead of the aforementioned trough.

Aviation 06z Monday through Friday
Shortwave ridging will maintainVFR through Monday with the only
interruption being the potential for peri-dawn fog. Zzv has the best
chance escaping morning restrictions; a cold front over the mid-west
is expected to bring mid upper-level moisture into the region near
12z and could shutdown the radiational cooling process to create fog.

Winds are expected to increase late afternoon Monday as a tight
pressure gradient forms with the approaching cold front.

Outlook
Restrictions are likely Monday night into Tuesday, including llws,
with a frontal approach, subsequent passage, and coincident rain.

NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
