What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Synopsis
A cold front will move through the area today, with chances for
showers continuing into Tuesday and Wednesday, as a trough of
low pressure remains centered over the great lakes. High
pressure will move into the area late in the week, with a slight
increase in temperatures. Another cold front will move into the
area late on Friday.

Near term until 6 am Tuesday morning
Surface low pressure is currently located near fort wayne,
indiana. The overall surface pressure pattern remains somewhat
convoluted, with as many as four separate trough axes forecast
to rotate eastward through the iln CWA between this past morning
and the overnight hours. The initial axis, which led to the
fine-line on radar, has mostly cleared the area. Next up is the
actual cold front -- marked by a clearing in the rain, a sharp
shift to wsw winds, and a drop in temperatures into the 50s.

Two additional bands of rain are expected to move through the
area later on -- one during the late evening and one during the
early morning. Pops were increased for the overnight hours in
order to cover these chances for rain, but heavy rain is not
expected. Wind grids were also a challenge, as the wind
direction is expected to change numerous times as the troughs
move through.

Short term 6 am Tuesday morning through Tuesday night
Large scale troughing over the great lakes will keep a cool and
moist weather pattern in place over the ohio valley through
Tuesday. With that said, subsidence behind the early morning
wave might help to keep precipitation to a minimum over the iln
cwa through much of the day. As the main axis of the trough
approaches late Tuesday afternoon into the evening, some light
rain may begin to again overspread the area from the northwest.

Strong cold advection at 850mb will be ongoing through the short
term forecast period, leading to steep low-level lapse rates.

Because of this, some gusty winds will be possible -- up to 30
knots in the northern sections of the forecast area.

Temperatures are expected to be in the 50s for highs, and while
some lower 40s to upper 30s are expected for min temps late
Tuesday night, the winds should keep frost potential low.

Long term Wednesday through Monday
Wednesday morning a potent upper level low will be pulling northeast
towards the hudson bay. 850 mb temperatures Wednesday will be a
degree or two below zero with clouds hanging around the area. This
will keep high temperatures in the upper 40s to lower 50s or close
to 15 degrees below normal. Thursday morning the upper level low
will pull northeast as the upper level trough axis begins to
modulate. A frost still looks possible Thursday morning, but it
doesn't look as cold as in previous model runs. Even tough skies are
forecast to clear surface high pressure is now pushed south with a
tighter pressure gradient slightly stronger winds across the area.

During the day Thursday low level thermal profiles will continue to
recover and with mostly sunny skies high temperatures will likely be
in the 60s. This warm up will be brief though as near 590 dm heights
off of the washington coast allows another potent shortwave to dive
south. Late Friday morning the surface cold front will be entering
our western zones with colder air behind. Pwats along the front are
expected to surge to around 0.80" and with sufficient upper level
jet support have gone ahead and raised pops.

Saturday through Monday the region will dry out with temperatures
falling 10 to 15 degrees below normal. 850 mb temperatures are
forecast to be only 5 degrees below zero which will easily make high
temperatures only in the upper 40s some days. Overnight lows will
also be near freezing Sunday and Monday mornings with surface high
pressure building in from the west.

Aviation 00z Tuesday through Saturday
Several bands of pcpn will continue to pivot up across the area
through the overnight hours as a series of upper level
disturbances move through. This will result in some variable
southwest to west winds through much of the night as the various
areas of pcpn move through. CIGS will also likely bounce around
from MVFR toVFR through the night. Have generally leaned toward
a more pessimistic MVFR cig forecast but confidence is not all
that great with this due to the variability. Vsbys will be
similar, generallyVFR outside of showers but dropping to MVFR
or lower in some of the heavier rain showers. Pcpn coverage will
decrease during the day on Tuesday as CIGS lift toVFR but a
chance of showers can not be ruled out through the remainder of
the TAF period. Breezy southwest to west winds will persist
through the day on Tuesday with some gusts to 25 knots or so
possible.

Outlook... MVFR ceilings and visibilities are possible at times
through Wednesday.

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.
