A hot and humid airmass will intensify as the weekend approaches.
Near term until 6 pm this evening
Fog low clouds will slowly burn off after sunrise and allow for a
return to sunshine. Showers may develop on the higher terrain, but
deep convection elsewhere appears likely to be capped by increasing
h8 warm air. Highs in the mid-upper 80s seem quite achievable after
morning stratus burns off.
Short term 6 pm this evening through Saturday
The main story this period will be heat humidity. An upper-level
ridge will amplify thru Fri night, with h5 heights well-above
normal. Swly return flow will continue to advect moisture into the
region, leading to oppressive heat indices Fri and Sat as temperature
climbs into the 90s.
The excessive heat watch remains in place, covering the entire
forecast area outside of the higher terrain. Although not all of this
area is expected to exceed warning threshold (apparent temperature
of at least 105f), all locations in the watch are expected reach
threshold for a heat advisory (apparent temperature of 100-104f).
Although humidity on Sat will be modestly lower than fri, apparent
temperature still is expected to exceed 100f in most locations.
Considerable instability will be present fri-sat as an elevated mixed
layer is advected around the NRN edge of the upper ridge into the nrn
conus. Despite the abundant low-level moisture, anomalous heights
and warm air aloft, will likely cap vertical convective development,
thus limiting thunderstorm potential outside of the higher terrain.
However, if a storm is able to develop during this time, additional|
intense storms could generate as high dcape will lead to potent
outflow that can help parcels overcome the thermal cap.
Long term Saturday night through Wednesday
The ridge will begin to break down Sat night through Mon as several
shortwave troughs impact the region. Periods of showers and storms
seem likely as considerable instability will remain.
The upper trough will dig farther south by tue, resulting in a
return to drier weather and temperature near or slightly-below
Aviation 08z Thursday through Monday
MVFR-lifr fog is forecasted at all PORTS through dawn.
Flight category will lift to MVFRVFR shortly after dawn at all
sites, andVFR by late morning, which will remain the case for the
remainder of the day.
Vfr conditions are expected to predominate thru Sat with little in
the way of precipitation, but this forecast could go awry if a storm
does manage to form, as conditions will be favorable for convective
regeneration on outflows.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
