area forecast discussion
national weather service tallahassee fl
914 pm est Sat jan 20 2018

Near term [through tonight]
02 utc surface analysis shows an area of high pressure near
columbus ga. Winds over our region had largely gone calm. Ir
satellite imagery shows the presence of an upper low moving along
the central gulf coast and considerable mid and upper level
cloudiness moving to the NE ahead of this feature. In fact, there
have been some weak radar returns showing up in the last 30
minutes, mainly over the florida panhandle and adjacent coastal
waters.

The local airmass is still fairly dry, but has moistened from 24
hours ago. While there is a fair amount of lift ahead of the
approaching upper low, moisture is at a premium. Even so, it
would not be too surprising to see some sprinkles or even light
rain overnight across north florida before the upper low moves
east of the region in the morning. Have made some slight
modifications to the pop grids overnight to account for this
possibility. With sufficient cloud cover now in place across the
eastern half of the forecast area, have also raised overnight lows
a couple of degrees.

Prev discussion [620 pm est]
Short term [Sunday through Monday night]
A +pv anomaly currently aloft of the west coast will swing eastward
into the plains Sunday night, generating a surface low pressure
system that will then sweep eastward. This system will bring showers
to the southeast Monday through Monday night. SBCAPE will be very
low, 200 j kg or less, so any thunderstorms would be pretty
isolated. With that said, models are also showing 0-6 km shear
around 40-50 kts, which could allow some marginally severe wind
gusts to occur in those isolated thunderstorms. Our best chances for
storms will be Monday evening to Monday night, however, when
instability will be waning, so the threat appears pretty minimal for
our area at this time.

Long term [Tuesday through Saturday]
The low pressure system will continue moving off to the east, with a
few showers possibly still lingering in our eastern zones Tuesday
morning. Behind the front, temperatures will be near normal for this
time of year, with highs in the 60s and lows in the 40s. Our next
chance of rain will be next weekend after a weak +pv anomaly over
central mexico helps develop a low in the western gulf.

Aviation [through 00z Monday]
Vfr conditions are expected through the period. Mainly mid and
upper cloudiness will move over the region this evening and thin
on Sunday.

Marine
Wind speeds will increase Monday ahead of a frontal passage and
remain elevated for the next several days in its wake. Seas will
build to 3 to 5 feet over coastal waters west of apalachicola Monday
night, then will lower to 2 to 4 feet by Wednesday.

Fire weather
No fire weather concerns.

Hydrology
Storm total rainfall for the upcoming frontal passage Monday night
is expected to remain below a half inch, will not cause any
flooding.

Spotter information statement
Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they
occur by calling the office or tweeting us @nwstallahassee.
