Discussion
Tonight and Thursday: potent mid level cold core low continues
spinning about over ar at the moment with a gradual drift to the
northeast noted in radar and satellite. Although the majority of
the forecast area has been dry slotted aloft, isentropic ascent
due to cooling in the column is still sufficient to support light
snows over the northern fringes of the forecast area for a few
more hours this evening. Further to the south, cold dry air in the
lower levels has begun working in from the west serving to slowly
erode cloud cover. Clouds will erode steadily from the southwest
tonight with plummeting temperatures behind the clearing line and
minimums in the mid to upper 20s by Thursday morning. Clouds will
hang on the longest over the northeast, but upper 20s still look
attainable there. This cold air tonight will effectively end the
growing season. Will keep the winter weather advisory running this
evening with the freeze warning in effect for the entire forecast
area overnight into Thursday morning.

Clear skies and full Sun will support a considerably warmer day
Thursday as compared to today with highs in the 40s and lower
50s. 26
Thursday night through Wednesday: a quiet period of weather will
persist through the rest of this week into the middle of next
week. A broad longwave trough will become established from
southern canada into the heart of the country by Friday. Northern
stream shortwave troughs rotating through the base of the mean
trough will stay well to our north due to a lack of amplification
in the synoptic scale pattern. The only exception will be Sunday
night into Monday when two fast moving disturbances are progged to
brush by just to our north and help push a dry cold front into
the area. This front will be moisture starved and only an isolated
shower or two are expected over the northern portion of the area.

Otherwise, the rest of the period will be characterized by
rebounding temperatures with highs climbing into the low to mid
60s by Saturday ahead of the aforementioned cold front Sunday
night into Monday. This cold front will be weak, however, and high
temperatures will still remain in the upper 50s to low 60s. There
are early indications that a pattern change could be in store
heading into the thanksgiving holiday and the following weekend.

Both the operational gfs ECMWF and their respective ensembles
support an active southern stream with several disturbances
ejecting out of the desert southwest into the deep south. It's
still too far out to speculate on any details, however the trend
will be for a warmer and wetter period. Tw

18z TAF discussion:
while ifr ceilings remain at most locations, visibilities have
begun to improve as the light snow and drizzle have tapered off
from the southwest. Ceilings look to oscillate between ifr MVFR
through the afternoon and evening with gradual clearing from the
southwest at pib, hbg, jan, hks and glh by late evening and the
remaining TAF sites after sunrise Thursday. 26

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.
