What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
A frontal boundary will remain in the region into the weekend
and will keep active weather in the forecast.

Near term through Thursday
Low pressure is slowly shifting to the east. Expect heavy rain
focus to shift eastward with it, though a few stronger cells are
still present on radar. Boundary is still situated over the
region, but this should sink southward overnight. Will keep pops
for areas along i-70 i-76 in SW pa and points south for much of
the night as showers will linger here. Have allowed the flash
flood watch to expire though some issues may continue in the
vicinity of the departing low for another hour or so.

Lingering cloud cover with the boundary in the vicinity of the
upper ohio valley will likely hold temperatures up a few
degrees overnight.

Brief period of shortwave ridging should keep the bulk of
Thursday dry, before the boundary once against starts to move
northward in advance of approaching low pressure. Stayed near
seasonal averages for highs.

Short term Thursday night through Friday night
Precipitation chances will increase Thursday night and Friday
as a warm front approaches the region ahead of a deepening
midwest trough. Cloud cover may limit heating a bit more on fri,
with temps in the 70s slightly below seasonal average. Surface
based convection looks unlikely based off model soundings but
kept a slight chance mention for storms as there looks to be
some elevated instability.

Long term Saturday through Wednesday
A strong low pressure system in the central plains will approach
the great lakes region Fri night and sat, with showers and
storms expected as it crosses. Given the expected negative tilt
of the system and strong forcing for ascent, the potential for
damaging wind gusts will need to be monitored despite the
less favorable timing of the sfc trough passage.

A subsequent shortwave trough could spell additional rain
chances on Sun before high pressure builds into the region on
mon and Tue and erodes much of the low-level moisture.

Seasonable temperatures should continue into next week.

Aviation 02z Thursday through Monday
Bulk of precipitation will start to shift south and east, but
restrictions will likely continue in MVFR ifr stratus and fog.

Models seem to be handling the degradation areawide, save for
kfkl and kduj but fog may develop here anyway since they too
received a period of rain. Gradual improvement is expected into
Thursday morning as the front sags southward and drier air
moves in from the north.

Light nne winds will establish Thursday morning.

Outlook...

a brief respite on Thursday will be followed by periodic
restrictions into the weekend as the front wavers across the oh
valley region.

Pbz watches warnings advisories
Md... None.

Oh... None.

Pa... None.

Wv... None.

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.
