an upper low sits just south of the great lakes with associated
troughing extending south through the mississippi river valley.

Farther to the west, sharp ridging extends from texas northward to
montana. Cooler and drier air is filtering in on the east side of
this ridge allowing for pleasant weather conditions for the next
couple of days. The ridge approaches the east coast through the
weekend before the next trough moves in by the start of next week.

On the surface, low pressure remains well to the north while high
pressure builds in from the gulf of mexico producing pleasant
weather for the remainder of the week and into the weekend.

Temperatures will be several degrees below average on Thursday and
Friday before a warm up on Saturday and Sunday. The next cold front
moves north of the area on Monday and Tuesday next week, with only a
slight chance of showers expected. The next brief cool down will
move in on Wednesday with daytime highs in the low to mid 70's. So
all in all, a relatively quiet weather pattern can be expected for
the next 7 days.

Marine... High pressure in the gulf of mexico ridges east
producing north- northwest winds at 10 to 15 knots. A slight
increase in winds around 15 to 20 knots can be expected
late Thursday into early Friday morning. This will be short
lived with winds 15 knots or less expected through the
weekend as well as veering winds to the east- southeast. No
other marine impacts expected.

Fire weather...

high pressure builds into the area bringing cooler and drier air for
the next couple of days. Relative humidity values will dip close to
critical values Thursday through Saturday, but winds are expected to
remain below 15 mph, so no red flag conditions are expected at this
time. No significant dense fog is expected.

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.
