Synopsis
Issued at 121 am edt Sat apr 21 2018
temperatures will continue to moderate through Monday as a weak
high pressure area remains over the region with highs in the
lower to middle 60s Sunday. Highs will finally rise above normal
Monday into the upper 60s to near 70. Small chances for showers
may arrive late Monday into Tuesday and again by Thursday night.

Short term (this evening through Sunday)
issued at 253 pm edt Sat apr 21 2018
touch of mid level forcing responsible for cloud cover and even
some sprinkles upstream will continue to weaken into early
evening. Can't rule out a stray sprinkle somewhere but not worthy
of anything in the grids, the clouds have put a bit of a damper
on highs thus far but not substantially. Clouds will thin tonight
into Sunday with increasingly warmer air arriving to send highs in
the 60s across the area for the afternoon. Strong mixing will also
allow lower dewpoints and respective humidity values than most
models are depicting. Manually adjusted for this as much as
possible.

Long term (Sunday night through Saturday)
issued at 253 pm edt Sat apr 21 2018
upper low will move slowly drift into the lower ohio valley
through Tuesday, eventually allowing for some moisture to be
thrown back NW in the area. Models continue to print out some
light QPF but dry air mass will likely be fighting hard warranting
a tempering of blended models to no more than slgt chc showers
initially and then low chc there after. Secondary wave will move
in behind it but impacts may be further south and limit moisture
return ahead of frontal boundary mid week. Still keeping with
period of chc pops thurs ngt on but low confidence on how things
will evolve. Warmest day still appears to be Monday with potential
for 70+ depending on amount of cloud cover. Temps will cool off
somewhat but back to near normal levels in the upper 50s to mid
60s so much better than what has been seen of late.

Aviation (for the 06z tafs through 06z Sunday night)
issued at 119 am edt Sun apr 22 2018
vfr flight conditions assured through the period. Thinning mid
level clouds later today as southeast ok vortex shifts east-
southeast into the tn valley.

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.
