Weather Blog: Thanksgiving Day Forecast

News

Surface high pressure currently across Eastern Arkansas is expected to begin pushing eastward today as a shortwave over the West Coast approaches the Plains.  

In response, southerly winds along with high temperatures close to yesterdays highs should be common across Eastern Oklahoma and Northwest Arkansas today.

Wind gusts 15 to 25 mph across Northeast Oklahoma combined with highs in the low 60s will again create areas of limited fire weather conditions this afternoon. A limited fire danger may remain into the overnight hours before relative humidities recover as southerly winds look to increase from west to east with the approaching shortwave from out west. 

A slight chance of rain showers will become possible over parts of Northeast Oklahoma late tonight into early Friday morning and become likely during the day Friday as the wave moves across the Southern/Central Plains.

The greater rain chances look to be across Northeast Oklahoma and Northwest Arkansas Friday morning into early afternoon ahead of the mid/upper level trof axis. 

Instability continues to look limited at best over the CWA and will thus continue with no mention of thunder. During the afternoon hours Friday…rain showers look to taper off from west to east behind the frontal boundary as it pushes across the CWA with chances exiting the region by Friday evening.

Behind the frontal boundary, clearing conditions will allow for a late afternoon temperature rally with highs in the upper 50s/low 60s over the western part of the CWA. Highs in the low 50s are forecast for Northwest Arkansas. 

Southerly winds quickly return along with the warmest day of the forecast period Saturday ahead of another wave and strong cold front forecast to move across the region Saturday night and Sunday.

Ahead of this system, temps in the mid 60s to low 70s will be possible. These conditions will help to create at least limited fire weather conditions over the CWA with some elevated fire weather dangers over parts of Eastern Oklahoma where the warm temps and higher winds should be co-located.
