Mesoscale Discussion 0024
NWS Storm Prediction Center Norman OK
1130 AM CST Thu Jan 09 2025
Areas affected...Central/North-Central TX
Concerning...Freezing rain
Valid 091730Z - 092130Z
SUMMARY...Freezing rain will be possible across portions of central and north-central Texas, with from 0.05” to 0.10” expected over the next several hours.
DISCUSSION...Regional radar imagery shows increasing precipitation coverage across southwest TX, coincident with strengthening warm-air advection and large scale ascent ahead of the shortwave trough moving out of northern Mexico. The northeasterly motion of this area of precipitation should continue, taking it into central/north-central TX over the next few hours. Temperatures across central/north-central TX are near freezing, but an additional degree or two of cooling is possible as precipitation cools the column, helping to offset some of the low-level warm-air advection. As such, the surface wet-bulb temperature, which has been gradually shifting northward, will likely stall along its current location, which is roughly along a line from BBD to SLR. Freezing rain will be possible north of this line over the next several hours, with total precipitation from 0.05” to 0.10” expected.

Note from NCOEM - we have been fortunate that this far today the freezing line has remained just to our north. We will have to monitor this as temps may cool slightly allowing for some impacts from frozen precipitation. Continue to monitor NWS and NCOEM for the latest updates. Our next update will come after both our NWS and County Stakeholder Meetings by 3:00 PM. #navarrocounty #ncoem
