Update
Current forecast is on track. No additional updates are planned
this evening. An updated aviation discussion is below the short-
and long-term discussions. Rms

Short term Valid for Tue and wed...

dry conditions prevail across the region this afternoon. A weak
shortwave is moving north to south across eastern most zones this
evening, however, bringing precip potential across that area late
this evening and overnight. Eastern zones have some potential for
patchy fog again early Tuesday morning, with enhanced potential
anywhere that does receive precipitation.

Otherwise, dry conditions will prevail through short term period,
as a strong upper level ridge moves eastward toward the region
from the pacific coast. Although snow cover continues to decrease,
it should still keep temps a little cooler for Tuesday. That
said, temps should be around seasonal average Tuesday for the
first time since early february, as the ridge approaches the
western zones.

Expect to see the warmest temps since early february on
Wednesday, with highs in the mid 40s to upper 50s across the
region.

Long term Valid for thu... Fri... Sat... Sun... Mon...

limited changes for the extended forecast period. Models favor
unseasonably warm conditions through the work week, with highs in
the mid 40s to upper 50s throughout the work week.

Models appear in good agreement, for the beginning of the extended
forecast period, so expect to see dry conditions prevail the
latter portions of the work week.

There is some indication that conditions become a bit more
unsettled by Friday night, and remains unsettled through the
weekend and potentially into Monday. An upper level low is progged
to lift northeastward from four corners region toward southeast
montana. Models do not agree well on how much this system will
impact the region, but have continued with inherited pops at this
time. Temperatures do appear to be slightly cooler, with passage
of the upper low, bringing temps back to around seasonal average.

This late period weather will require attention as details become
more certain.

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.
