A shallow arctic airmass is still hanging on across northeast Oklahoma with a sharp discontinuity in dew points as well as wind direction near I-40 early this morning.
The boundary will retreat later today being replaced by a more moist airmass, with a resultant warm up.
It will be tempered by low clouds expanding north out of Texas, especially south of I-40 where temperatures may be similar to what was observed Wednesday.
Weak isentropic lift could result in a few light showers tonight, with the continued influx of low-level moisture leading to patchy drizzle.
Shortwave off the California coast this morning will move east in a weakening state, but still may provide enough lift to increase the chance of light rain across southern areas Friday night into
Saturday. The warming trend will continue through that time but with widespread low clouds remaining rather persistent.
A weak Pacific front will push through and bring a slight cool down Monday, but still well above normal temperatures expected the early part of next week. Models this cycle have trended toward a less amplified system midweek, with precip chances lowered a bit Tuesday from previous forecasts.
A strong cold front will eventually push south in the wake of this system but still appears that cold air will lag well behind any precip.
