New FWNWS:
LONG TERM... /NEW/
/Wednesday Night through Early Next Week/
An active period will take place Wednesday night through Friday
as the potential for winter precipitation continues to increase
across North Texas into portions of Central Texas. As expected,
there are still many uncertainties about precipitation types,
rain/wintry mix transition zones, and snow/ice accumulations.
We`re continuing to piece together what we know, what the models
are telling us, and what Mother Nature will actually deliver.
One good news is that in the synoptic scale, models are overall
coming into a more consistent solution with the upper low staying
over Baja California a little longer which may bring a slightly
warmer airmass into the southern Plains just in time as the
precipitation arrives. One of the reasons forecasting winter
weather in our area is so challenging is the variability in the
temperature profiles shown in the guidance. Not only can this
change the snow and/or ice accumulations but also the transition
zones. The most likely scenario at this time continues to be the
potential for mixed precipitation for most of North Texas and
portions of Central Texas. This doesn`t mean that everyone will
see winter precipitation, some locations may see more cold rain
than any other type.
So, what`s new with this update? A Winter Storm Watch has been
issued for the entire North Texas region from early Thursday through
Friday. Given the trends with the track and the progression of the
system, confidence continues to increase that a band of
moderate/heavy snow could impact portions of North Texas. At this
time, the highest snowfall accumulations appear to be north of I-20
towards the Red River where 3-6" of snow are possible. While the
totals for portions of Central Texas are lower, we continue to
monitor the potential for some ice accumulations as freezing
rain/sleet could mix in with the rain. As expected, continue to pay
attention to the forecast as these amounts and precipitation
types will continue to be adjusted.
What we would like to be the main takeaway is that this system is
expected to bring at least a medium likelihood of moderate
impacts for portions of North Texas especially travel impacts.
Continue to take the necessary precautions, prepare your home for
the cold weather, and consider alter any travel plans later in the
week.
The precipitation is expected to end Friday afternoon/evening,
but impacts will continue to linger into Friday night and Saturday
morning as temperatures remain or drop to below freezing during
the night. Dry weather will continue over the weekend with
temperatures warming into the 40s/50s Saturday afternoon for most
locations. Beyond that, high pressure will settle early next week
with dry but cooler weather with highs in the 40s and lows in the
30s.
