Synopsis
Dry weather is expected through mid week under high pressure. Rain
chances return with a late Wednesday warm front, and again with a
Thursday cold front.

Near term until 6 pm this evening
Stratocu should continue to erode before sunrise with increasing
subsidence under building high pressure. An increase in high clouds
is expected as cirrus from decaying convection across the plains moves
across the area. Highs are expected to be around 5 degrees below
average.

Short term 6 pm this evening through Thursday night
Dry weather should continue through most of Wednesday under a
building ridge, though mid and high clouds should increase in warm
advection. The ridge is progged to flatten some late Wednesday and
Wednesday night as a shortwave and its associated warm front
approach and cross the region, spawning scattered showers and
thunderstorms. Marginal shear and instability could result in
isolated strong storms in the late afternoon evening, though warm mid
levels and poor lapse rates appear to be the main limiting factor.

After a break in the rain Thursday morning, more showers and storms
are expected Thursday afternoon and night as another shortwave and
sfc cold front cross the region. Kept coverage in the scattered range
as the best upper support is progged to be north of the area.

Temperatures are expected to average above seasonal levels.

Long term Friday through Monday
A ridge extending from the gulf coast to the midwest is progged to
move E and build over the upper oh valley region Friday, with dry
weather expected. The ridge is progged to flatten over the weekend
into early next week as shortwaves cross along its northern
periphery. This should result in periodic, scattered showers and
thunderstorms. Above average temperatures are expected to continue.

Aviation 07z Tuesday through Saturday
MVFR to lowVFR stratocu is expected N of I 70 tonight with moisture
below a temperature inversion. The clouds should erode from n-s late
tonight as subsidence increases under building high pressure.VFR is
then expected through the rest of the TAF period under the high,
though mid level clouds should increase in warm advection.

Outlook
Restrictions are possible with crossing disturbances late Wed and
thu, and again sat.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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 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.
