Big Temp Ranges Today

Expect a broad range of temperatures today with highs in the upper to mid-40s across northern Ok and lower 60s across southern sections.  

The incoming 06 NAM is not quite as robust in bringing the warmer air south and consequently keeps most of northern Ok in the upper or mid 40s later this afternoon with much warmer air across southern sections of the state.  This is very common with a shallow cold air mass.  Locations across north Texas may be very close to 80 today while southern Kansas will stay in the lower 40s.  The Tulsa metro will be around the 48 to 50 range with increasing clouds and gusty north winds this afternoon. 

 Low clouds are noted this morning advancing from north Texas into southeastern OK.  The 06nam brings the clouds into eastern OK while keeping the areas along and west of I-35 mostly clear.  Needless to say, the "bust potential" remains high regarding the forecast for the next few days.  I have lowered our highs in the Tulsa metro to 49 while keeping the McAlester area near 60.   

The temperatures tomorrow should be on the cool side with morning lows in the upper teens or lower 20s and highs in the lower to mid-40s.  Sunshine will be likely for the day with east to southeast winds around 10 mph.   

Another clipper like system will move across the area Sunday but not before we'll warm into the upper 50s and lower 60s.  The temps could take a dive Sunday late afternoon into early evening as colder air aloft spreads across the region. A few sprinkles may be possible Sunday across extreme eastern OK, but most of the area will remain dry.  The EURO is a little more robust with the precip chances and would even offer a chance of a storm or two across western Arkansas.  The areas in central Kansas could see a few snow showers or brief flurries Sunday evening but this would stay north of our immediate area of concern.  

The Tuesday and Wednesday period will feature a strong looking system approaching from the west that should increase the rain and storm chances for Texas and possibly portions of Oklahoma. We're continuing to monitor the computer data and have increased the probability for the Wednesday time periods.  The models continue to offer no run to run consistency regarding the exact outcome for the Wednesday period, including the temperatures.  The 00GFS would even suggest a shot of wintry precip Wednesday across northwestern or central OK, while the EURO would keep the profile to warm for any wintry precip.  Stay tuned for more updates.
