Synopsis
High pressure will build across the region today. A weak
canadian clipper will move across the area Monday spreading
some areas of light snow across the region. Another canadian
clipper with an associated cold front will move through the
area Tuesday with scattered rain or snow showers. Colder weather
returns late in the week as canadian high pressure builds
southeast into the region. Another system will approach from the
west Friday and may spread precipitation across the area by late
in the day and into the weekend.

Near term until 6 pm this evening
640 am update: clear skies across the region as high pressure
builds over the region. A very cold early morning start due to
the early morning radiational cooling. Input latest mesonet
data. Made some adjustments to be colder for temps over the
next few hours, otherwise no other changes needed.

will be colder with highs in the teens and 20s. Winds will be
generally light from the northwest.

will approach from the west and move across the region on

maybe an inch or so of snow accumulations may occur in some
areas. Rfcqpf looks good. Used a blend of model temps suggesting
highs mainly in the 20s.

more southwesterly. Several short waves will move through the

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.
