Short term Today through Tuesday night
fire danger concerns will continue to be the primary forecast concern
in the short term period...

moisture levels remain low early this morning... With dewpts
remaining in the 20s to near 30. Winds remain light... But the sfc
pressure gradient will tighten later in the morning. Expect SW winds
to increase to 15 to near 20 kts across the ozarks and ms delta
region of the cwa... With 10 to 15 kts expected across central to sw
portions of the cwa. Winds will then switch to the west and NW as a
new front drops SE into the CWA this afternoon. Expect the wind
speeds to be similar at 15 to around 20 kts across NW and nrn
sections of the cwa. Expect gusts exceeding 25 kts in these same
areas.

These winds will combine with very dry air near the sfc... With dewpts
remaining in the 20s to near 30. However... Temps will warm above
normal... With highs this afternoon in the 60s to mid 70s. This will
result in min rh values dipping below 25 percent for most
areas... And as low as 15 percent for a few isolated areas across the
ouachitas and ozarks. Many areas will see red flag conditions
develop with these conditions coming together... With rh values
dropping at or below 25 percent... 20 ft winds of 14 mph or
greater... And 10 hr fuel moisture levels of less than 10 percent. In
fact... All of ar has 10 hr fuel moisture levels of less than 8
percent... With some areas down as low as 5 percent across the nw.

The only areas that may not seen all criteria met for a red flag
warning will be the SW quarter of the CWA due to winds at 20 ft
staying around 8-12 mph. However... Both rh and fuel moisture levels
are low enough... And these same areas are placed in an extreme
drought. For this reason... Will include all counties in the CWA in a
red flag warning for 16z-00z.

Fire weather concerns will persist into tue... But expect cooler
temps to result in higher rh values during the afternoon hours. Even
so... Very dry air will remain in place and no precip is expected.

Temps will be about 20 deg cooler... With highs back into the 40s and
50s.

Long term Wednesday through Sunday
the extended forecast will mainly remain dry, with temperatures
around normal to above normal values. The elevated wildfire danger
will also continue across ar.

Wednesday will start with a surface high pressure system to the
south of ar, while an upper low pressure trough was over the eastern
us. An upper level northwest flow will be into the region, while a
south wind flow into ar will help warm temperatures on Wednesday.

Late Wednesday night to Thursday, the upper northwest flow will
allow a system and cold front to move through the region. Limited
moisture is seen, and the forecat will remain dry and with only some
clouds. Behind the cold front, a northwest wind and cooler air will
filter in over the area, and with cooler temperatures. Into Friday,
the upper low pressure trough deepens, and allows the surface high
pressure to settle in over the region. Temperatures on Friday will
be a bit below normal.

Over the weekend, the surface high pressure is forecast to settle
south of ar, and a south wind sets up again, while the upper pattern
will become more zonal from the west. GFS model forms a surface
system on Sunday, with some possible chance of rain in the forecast
late Saturday night to Sunday, while mainly in the east on Sunday as
the system moves east. The euro is drier with little to no rain
forecast. Have taken a low end approach with a slight chance of rain
due to the uncertainty in model runs. Fine tuning will be needed as
we approach the weekend. Temperatures over the weekend will be
overall warmer than normal.

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.
