Synopsis
Issued at 212 pm edt Wed aug 21 2019
a cold front will drop south through the region tonight with
chances for showers and thunderstorms along it. The best chance
for rain will be near and south of route 30. It will be cooler
and less humid Thursday through Saturday with mostly clear skies
and very comfortable conditions for late august.

Short term (this evening through Thursday)
issued at 256 pm edt Wed aug 21 2019
monitoring two features in the short term. The first is a cold
front that is slowly dropping south out of southern wisconsin and
central michigan. The second feature is a complex of showers and
thunderstorms associated with an mesoscale convective vortex
centered over western illinois. Model guidance leaves something
to be desired at this time, but hint at widely scattered storms
along the cold front, and much of the leftover MCV activity
tracking through the southern half of the county warning area
tonight. Thursday will be less humid for locations toward the in-
mi state line, before spreading south. Until the cold front fully
pushes through the area, will carry some pops in the vicinity of
the front.

Long term (Thursday night through Wednesday)
issued at 212 pm edt Wed aug 21 2019
high pressure will finally suppress any precip chances, with the next
chance for rain now arriving until late Monday into Monday night as
series of upper level waves carve out the ridging aloft. Few changes
to model blends at this stage with variations in highest pops likely
given likely timing differences.

With regards to temps, cooler and less humid conditions will prevail
with highs in the 70s through Sunday before warmer temps and higher
humidity begin to creep back in with the expected increase in rain
chances.

Aviation (for the 00z tafs through 00z Thursday evening)
issued at 736 pm edt Wed aug 21 2019
cold front to slowly sag south overnight. MCV seen nicely on
satellite but only generating some light showers on radar at this
time. Models rather aggressive in developing showers and a few
tsra along this boundary overnight as several weak short waves
propagate east and theta E moisture pools along boundary. Have
stayed with previous forecast for consistency with pcpn mainly
south of ksbn but likely getting into kfwa. Did not introduce
thunder at this time given low probs for any single point. Winds
turn north to northeast. Winds become light overnight but expect
clouds to linger and hold fog development in check. However, any
clearing could lead to patchy fog once again toward daybreak.

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.
