Evening Weather Update
…Rain chances on the increase for the first half of the upcoming
weekend…a few thunderstorms will be possible too along with chilly temps…no
severe weather is expected...
An active subtropical jet (southwesterly wind flow aloft) is to
blame for the persistent and widespread high cloud coverage. At the surface, a
weak cold front is moving across the region and will help to reinforce the
cool, dry air mass in place across the area. Lows tonight will drop into the
upper 30s to middle 40s across the area under a mostly cloudy sky. Those clouds
and a northerly breeze will help to keep temperatures above the freezing mark
across the area. Some sprinkles may try and approach the area late tonight from
the south, but given the extremely dry air in place at the surface and the
majority of the upper level dynamics to produce rain staying to our south, most
locations will likely remain sprinkle-free.
Friday’s
Forecast:
A chilly start to the day in the upper 30s-mid 40s will give way
to a mostly cloudy and cool afternoon with highs only managing the mid-50s to 60°F.
Rain is not expected across the area on Friday.
Weekend Forecast:
Rain is likely on Saturday (especially during the afternoon and
evening hours) as an upper level disturbance moves across the area from west to
east. A few thunderstorms cannot be ruled out on Saturday, but no severe
weather is expected. Given the widespread clouds and rain, highs on Saturday
will likely stay on the chilly side in the 50s. It’s definitely going to feel
cold and damp with the rain.
On average 0.5 to 1 inch of rain could fall for areas along and
east of the I-35 corridor, with lesser amounts likely for areas west of the
Highway 281 corridor. Rain will clear out from west to east late Saturday night
into Sunday and set the stage for a pleasant Sunday with mostly sunny skies and
afternoon highs in the 60s.
Early Look at
Christmas:
Long range models have consistently been hinting that some
significantly colder weather (Arctic Air) looks to arrive the Friday before Christmas
(12/22) and perhaps drop highs into the 30s and 40s and overnight lows into the
20s. Those same models predicting the cold air moving in are also showing chances
for wintry precipitation across the area too. It’s too early to say how cold it’s
going to be and just how much if any precipitation we will see, but it’s worth
noting that the weather trend is looking to be much colder and potentially
wetter as we head into Christmas. Stay tuned.
