Futurecast

9am Saturday Update:  Scattered icy spots on bridges improving as temperatures over most of the Arklatex rise above freezing.  Still have some light rain in spots this morning over the southern half of the area.  Not expected to cause any further issues as temperatures continue to warm.  The Winter Weather Advisory issued by the National Weather Service has expired.

130am Update:  Not much chgnge during the past several hours.  Latest radar shows light rain over the southern half of the area.  Temperatures remain slightly above freezing.  Temps could still drop to freezing or below creating some slick spots on area bridges and overpasses.   Winter Weather Advisory continues for E TX and NW LA.

930pm Update:  NWS removes several counties from the northern edge of the Winter Weather Advisory.   Most precip will stay south of AR-LA state line.   Slick spots will be possible on bridges when and if temperatures dip to the freezing mark.  The new overpasses at the I-220 & I-49 interchange have been closed by LA DOTD.

830pm Live Winter Wx Update:

4pm Live Winter Wx Update:

Light winter mix expected across the Arklatex tonight.  Warming trend to begin this weekend. Heavy rain returns to begin next week.

Friday was a cold day around the Arklatex.  Temperatures began in the 20s all across the area.  That cold air has been trapped beneath what we call an inversion above us keeping temperatures in the low to mid 30s Friday afternoon.  These temperatures are much colder that what models have projected so when and if any precipitation begins to fall, it is likely that it will come in a mix of sleet and snow. The wild card in the developing scenario is that we have some VERY dry air above us.  Radars are showing  precipitation falling from the clouds above us but it is evaporating before reaching the ground.  The big question remains will we be able to moisten the air above us enough to allow the precipitation to begin.  I do anticipate seeing some light sleet/snow at some point late today through tonight.  Some minor accumulation will be possible on exposed surfaces.  That means we could see some slick spots on untreated bridges and overpasses when and if the precipitation begins.  If you are driving this evening or tonight and notice any precipitation please slow down and use extra caution.

Keep an eye on the latest from Futurecast below. It is showing rain but given that we have not warmed up at all today, any precip that falls will likely be a mix of sleet and snow.

Saturday will likely be a mainly dry day with a cloudy sky.  Temperatures will begin in the low 30s and will struggle to make it into the low to middle 40s. If we have any slick spots leftover Saturday morning they will quickly normalize during the early morning hours. The first in a series of disturbances will roll across the area starting Saturday night through Monday night.  Models are still indicating that several inches of rain will be possible during this period. Even though we will see lots of rain and some thunder Monday, I don’t expect any severe weather.  Look for much warmer temperatures to return to end the weekend and begin next week.  Highs will return to the 50s and 60s.  A few 70s will be possible Monday.  Overnight lows will return to the 40s and 50s.  

We will see a dry period for most of Tuesday and Wednesday.  Another system will then move over the area and bring more rain Thursday and possible Friday.  

Average High/Low for today’s date: 60/38.
