Statewide Forecast Discussion:


Issued: 8:46 AM CST (1446Z), Thursday, January 23, 2020

...SYNOPSIS...
A powerful mid-level trough continues to dig southward into northeastern Oklahoma this morning, deepening as it does so. After this trough moves out tomorrow, an active pattern will persist with an amplification of the jet regime looking increasingly possible late next week.

...SHORT TERM...
Current satellite imagery shows an impressive negative tilt trough pivoting eastward over central Kansas this morning. Its associated cold front has moved southeast of the state, however, northwesterly surface winds will strengthen as the surface pressure gradient tightens. This is the result of the aforementioned trough further deepening as it enters northeastern Oklahoma. Clearing skies across the northeast in conjunction with steep mid-level lapse rates will encourage very marginal destabilization of airmass ahead of intense CPVA in this region. Enough elevated moisture will exist for the development of southeastward moving cold core shower activity. While the overhead jet streak will be displaced to the west from these showers, enough downward momentum transport appears possible to encourage gusty winds with this activity later this afternoon. By nightfall, the temperature will dip near freezing and allow some snow to mix in. No impacts are expected. Elsewhere, highs in the 50s with low dropping into the 30s.

...LONG TERM...
As mentioned in yesterdays discussion, the synoptic regime is expected to remain active over the coming days. Rain, albeit light and short-lasting, looks possible again Saturday night into Sunday. After this system, another trough will move in Tuesday into Wednesday providing another chance for precipitation. This one may be cold enough for some winter weather over northern Oklahoma. Models have de-amplified this system significantly and no longer appears as potent as previous model runs showed. Still, no major cold fronts look likely over the next 5-7 days. Beyond that, models hint to an amplified jet pattern.
