.SHORT TERM /Today through Friday/...
The current satellite loop shows some mid to high level
clouds associated with the secondary frontal system moving into NW
GA. These clouds will stream across the state as this front is
expected to sweep through the region today. This second front is
much drier than the one that went through Tue and Wed and is the
main boundary ushering in a much cooler and drier airmass. High
temps today will only get up into the upper 60s across the NE GA
mountains to the mid 80s across central GA. Low temps Friday morning
will be in the Mid 40s across the NE GA mountains to near 60 across
central portions of the state. These lower temps will be a much
needed break from the 90 deg temps we have seen for a few months
now. Relative Humidity values will be mainly in the 30 to 40 percent
range across the area Today and Friday. All in all looking for cool
dry weather over the next few day.
.LONG TERM /Friday Night through Wednesday/...
The extended portion of the forecast remains quiet.
High pressure at the surface will dominate for much of the extended
forecast. The surface ridging begins to weaken by the end of next
week as a cold front begins to approach the Mississippi River.
Aloft, a long wave trough will dominate across the eastern US
through early next week. By the middle of the week, ridging begins
to build across the area. So, will all of this said, a dry and
seasonable forecast will hold.
One thing to keep an eye on though, is the progression of TS
Matthew. For now, both the GFS and ECMWF keep the storm well to the
east of the CWFA.
Fuel moistures dipped to below 8 percent across the northern and
western portions of the CWFA yesterday afternoon. For today, RH
values will remain around 30 percent, but will have to be watched
in case values are lower than anticipated. Winds are expected to
be out of the northwest at 10mph with occasional gusts to 15mph.
If RH values do begin to approach 25 percent, a the issuance of a
Fire Danger Statement will have to be considered. &&
.AVIATION... 06Z Update... VFR conditions with no precipitation
or restrictions to VSBYs expected. This is going to be mainly a
wind forecast. Winds will stay out of the NW through the period
but wind speeds will be the issue. Winds are 5kt or less but wind
speeds will increase into the 10-12kt range gusting to 20kt by 18z
this afternoon. The winds will increase as the secondary cold
front sweeps through the state today. Expecting wind speeds to
diminish shortly after 00z Fri to 10kt or less.
