Short term (this evening through Saturday night)
issued at 330 pm edt Fri aug 18 2017
the weather will stay fairly quiet this weekend. Fair weather cu
field will diminish this evening, along with the westerly breeze.

Drier air has advected into the region, with afternoon dewpoints in
the low to mid 60s. Skies will be mostly clear this evening and for
the first half of the overnight period. Mid-level cloud cover is
expected to increase early Saturday as an upper trough swings in.

Lows tonight will be in the mid upper 60s. Patchy fog will be
possible Saturday morning, especially near rivers.

Low pressure over iowa this afternoon is forecast to track east
across il in tonight, dragging a weak boundary with it. Moisture
isn't very deep and will be confined mostly to the mid-levels.

Still, a few showers are possible Saturday morning, mainly north of
i-64. Saturday will feature a mix of Sun and clouds, with highs in
the mid upper 80s. Ridging Saturday night will bring continued fair
weather with lows in the mid 60s.

Long term (Sunday through Friday)
issued at 345 pm edt Fri aug 18 2017
Sunday and Sunday night...

ridging will build in at the surface and aloft over the southeast
united states, resulting in dry weather and typically warm
summertime temperatures.

Eclipse day...

upper ridging will remain in place as the surface high shifts off to
the east. While southerly return flow does develop, it should remain
light. The 12z versions of the gfs ECMWF gefs continue to feature
quite a bit of dry air in the low and mid-levels. Scattered high
clouds are still a possibility, so am featuring a 25% sky cover
forecast around the time of the eclipse. Convection will likely be
ongoing across parts of the midwest, like iowa and northern
illinois. As long as it's not overly thick, thin cirrus may not mess
with eclipse viewing too much. And the brief cooling from the
eclipse itself may help to limit diurnal CU formation.

The day is likely to be dry and hot, with MAX temps around 90
degrees. Folks planning to be outside for an extended period should
dress for the weather and stay hydrated, as heat indices will likely
reach the mid 90s just before and after the eclipse.

Tuesday-Thursday...

a cold front will sweep through the region from northwest to
southeast Tuesday and Wednesday, accompanied by showers and
thunderstorms. Pacific high pressure will then come in with dry
conditions Wednesday night and Thursday. Heat index values should
again climb into at least the middle and possibly upper 90s Tuesday
afternoon, but then cooler conditions can be expected Wednesday and
especially Thursday.

Aviation (18z TAF issuance)
issued at 140 pm edt Fri aug 18 2017
this TAF period features largelyVFR weather. The one exception is a
possible brief period of MVFR fog from 09-12z Saturday.

Scattered CU field is established around 4500 ft this afternoon,
with a 10 kt wind out of the west. Expect these clouds to
evaporate and winds to diminish and turn southwesterly after 00z.

Mainly clear skies are expected tonight. Mid-level clouds are
forecast to increase toward 09z Saturday an an upper level trough
approaches. A few light showers can't be ruled out north of i-64
Saturday morning, but the potential was too low to include in the
taf. Lex has the best shot at seeing a brief period of MVFR fog
Saturday morning. Otherwise, Saturday will beVFR.

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.
