Winter Weather Potential - January 20-27

Recommended Posts

On a side note from winter weather, there looks like there could be a decent squall line move through this evening with some gusty winds. Keep that in mind tonight! Could be entertaining!

Ok, I've been playing today. So for your viewing pleasure, we're going old school. Here's your "Local on the 8's" the way the Weather Channel USE to do it in the early 90's, and this is real live data. 🙂

Even picked out the music myself. :classic_biggrin: It's too bad I can't schedule this to upload to my website. 

 

thanks. there is a tear in my eye.  seriously this brings back great memories.

You’re not wrong there’s a heck of a line coming AL right now.

  northeast Georgia and northwest Georgia...including the
  following areas...in north central Georgia...Cherokee...
  Dawson...Fannin...Gilmer...Lumpkin...Pickens and Union. In
  northeast Georgia...Towns and White. In northwest Georgia...
  Bartow...Catoosa...Chattooga...Dade...Floyd...Gordon...
  Murray...Walker and Whitfield.

Sitting here thinking how about how perfect that storm from December would be right now with a real cold air source to the North... Might not be perfect for everyone but a lot of North Georgia would see snow with a look like that right now. And most of the mountains would probably set a new snowfall record.

NWS Atlanta afternoon update

Quote

High pressure and fair weather will be the rule for much of the long
term forecast period. However, a sharp cold front and colder
temperatures are expected by the end of the week. This system will
bring some potential for wintry weather across a good portion of the
CWFA.


Dry conditions and near to slightly below normal temperatures are
expected through the first half of the weekend. Both the ECMWF and
GFS are progging a shortwave and weak frontal boundary to impact far
northern GA by late Sunday into early Monday. Neither model is
producing much precip with this system, but the ECMWF is slightly
wetter and further south with the shortwave energy.

The next system is expected to impact the CWFA Tuesday in the form
of a sharp cold front. Much colder air is anticipated on the back
side of this boundary, and there is some potential for wintry

weather before all of the low level moisture clears out. Kept the p-
type as ra/sn as it it way to early to nail down specifics. For now,
the chances for precip remain low, but will have to continue
monitoring.

Yep, we've sure wasted a lot of good moisture so far.

Mesoscale Precipitation Discussion 0022
NWS Weather Prediction Center College Park MD
321 PM EST Wed Jan 23 2019

Areas affected...Enter areas affected

Concerning...Heavy rainfall...Flash flooding possible

Valid 232016Z - 240300Z

Summary...Locally heavy rainfall remains possible across portions
of southeast MS, southern AL into portions of GA/TN/NC this
evening. 1-3" will be possible with the greatest risk of 3-4"
totals across southern AL. This may lead to localized flash
flooding through 03z. 

Discussion...Ahead of a broad mid/upper level trough moving
through the central/southern US, a surge of Gulf moisture has
advected northward, bringing PWATs of 1.5" into portions of
southern MS/AL. A recent RAP analysis showed a narrow axis of
MUCAPE of a few hundred J/kg as far north as central AL, as a warm
front gradually lifts northward.

Across southern MS and AL, there is a narrow time range where the
best forcing and limited instability overlap across southeast MS
and into southern AL where hourly rain totals of 1 to locally 2"
will remain possible. The mean flow remains favorable for training
and repeating rounds of storms with 850 mb winds out of the
southwest at 50-60 kts. There is a decent signal seen in the
hi-res models and supported by the HREF mean for areal averages of
1-2" through 03z with localized higher amounts reaching 3-4".
These types of totals could support localized flash flooding,
particularly over sensitive and urban areas.

Further north across northern GA, eastern TN, and southwest NC,
moderate rainfall is expected for a several hour period through
this evening all within a broad area of isentropic lift. Although
rainfall totals will be on the lower side (1-2", locally higher
amounts possible), this rainfall falling on colder/harder grounds
in terrain areas could result in flooding and possibly isolated
flash flooding. Hi-res models are suggesting the higher totals
could fall across far northern GA into southwest NC, particularly
within any upslope/favored areas.
