Tracking A System

A very slight chance of a sprinkle or snow flurry will remain today across the eastern part of the state.  A higher chance of a light dusting of snow will continue across western OK this morning as an upper level system moves into the region.  

This morning the radar is indicating a large area of snow across the Texas panhandle region with some drizzle or light rain extending into Oklahoma along the I-40 corridor.  Very little of this light precipitation has penetrated the layer of dry air just off the surface this morning.  This process is a cooling process and eventually some light precipitation will be expected along the I-40 corridor. We'll have a chance of some light drizzle or maybe a flurry this morning, then a chance of light showers this afternoon, followed by a chance of light flurries tonight.  But these chances will remain very small with most locations near 20% across northern and southern OK.  Higher chance will remain across the western half of the state. 

The afternoon temperatures for the eastern OK vicinity remain problematic for today.  Model output data continues to indicate warmer air today with highs in the upper 40s, but with abundant clouds and the threat of precipitation, I have kept our temps in the lower 40s.  The precipitation type will remain a mix of possibly flurries or sprinkles but no significant precipitation is expected across the eastern portions of the state.  As the system leaves the region tonight we may see a few flurries across far eastern OK as temps drop into the upper 20s and lower 30s. 

As this system moves eastward tonight the clouds will begin to thin out with Saturday featuring afternoon highs in the lower to mid 40s with mostly sunny conditions. 

A relative warm up will commence Sunday through Tuesday before another shot of cool air arrives Tuesday through Thursday. 

The upper air pattern will remain conducive to bring additional storm systems into the region next week, but model data indicates very little chance of any precipitation makers arriving.  

Euro data this morning is now hinting at a system arriving Friday, Christmas Eve with mid 50s Friday afternoon falling into the upper 30s for highs on Christmas Day.  The data currently supports no significant chance of precipitation but stay tuned for updates.
