Slow Warm Up Begins On First Day Of Spring

After a very chilly afternoon yesterday, we’re slowly warming up over the next few days.  We’ll eventually be moving back into the 70s by late this week with a few folks hitting the 80-degree mark before another system-cold front moves across the state.  In the short term, chilly weather is underway this morning with many locations in the lower 40s with mostly cloudy conditions along with a cool north breeze.  One last lobe of light precip is brushing far southeast Kansas and northeast Oklahoma early this morning but will be gone by the time most folks are up.  The clouds will eventually clear from the west to east as the day progresses and this will allow the metro region westward to move into the mid to upper 50s for afternoon highs while far eastern Oklahoma may stay in the lower to mid-50s for daytime readings.  Clear sky and cold weather will be likely Wednesday morning with many locations in the lower 30s.  South winds will return Wednesday afternoon with highs reaching the lower or mid-60s.   Daytime highs in the 70s will follow for Thursday and Friday.

The upper air pattern will feature a northwest flow for the next few days before flattening and transitioning back to a southwest flow Friday into the weekend.  This will eventually bring another short-wave disturbance across the state Saturday with another stronger looking short wave ejecting into the northern plains Sunday.  This first wave will shove another surface low across southern Kansas Friday night into Saturday, but very little moisture will be likely across eastern Oklahoma.  The leading edge of a few showers or storms may develop near us Friday but quickly move northeast into Missouri for most of the day with warm air overspreading the southern plains.  Our highs Friday should be in the mid to upper 70s.  Friday night into Saturday as the surface low ejects, a surface front will move across the state by the afternoon bringing north winds and pleasant weather into eastern Oklahoma with daytime highs still in the upper 70s or even the lower 80s.   The second northern plains low will help send a stronger surface front southward into the area sometime Sunday night or Monday with north winds and slightly cooler weather.  Some important synoptic scale features are different for this period when comparing the various data.  Changes are likely to occur but the trend of introducing some storms Sunday into early next week appears good at this point.
