Seems like most of the cold air advection stopped going further south once this front got into north TX. What’s the hold up? I saw that the models were indicating this happening as far back as last week. I mean for folks up in north Texas and Oklahoma, this front is just about on par with the last front we had this past weekend.
Its the Southwest flow aloft... From HGX morning discussion
Behind the front, cold air advection is making its entrance across
Southeast TX with sfc dewpoints quickly falling into the upper 30s
across the Brazos Valley early this morning.
A drier airmass will
continue to spread across the entire region; however, temperatures
will be a bit tricky. 925:850 hPa winds remain from the west-
southwest component, resulting in warmer values, especially along
the coastal zones. With this level of uncertainty, have leaned
towards the 25th to 50th percentile of climatology for today`s highsto produce temperatures from the mid 50s to upper 60s north of I-10
and from the upper 60s to near 70 south. It will also be breezy this
afternoon as pressure gradient tightens with the sfc high centered
over the Plains. Light winds, mostly clear skies and continued CAA
will result in a cold night. Overnight lows will drop from the upper
20s to mid 30s north of I-10 (colder readings in the Brazos Valley)
and from the mid 30s to upper 40s south of I-10 and along the
Islands.
