Highs temperatures today will stay in the 70s across far northern OK and into the lower 80s across part of southeastern OK.   The warming trend will remain for the rest of the extended forecast until the middle of next week when another front will near the state with a chance for additional showers and storms followed by a modest cool-down.   

Weather Alerts

An outflow boundary moved across the area yesterday at midday with a round of showers and storms remaining across eastern and southeastern OK yesterday afternoon.  The combination of the residual moisture at the surface combined with light winds and a broken to clear sky late last night allowed the development of fog overnight in some locations. The fog will be locally thick in many spots this morning through the 9am to 10am period before temperatures begin lifting away from local dew points and the fog dissipates.

 A dense fog advisory was posted for part of central OK through 10 a.m. then extended through 1 p.m. One of the forecasting issues today will involve how long any fog will last and the impact on the temperature trend for the day.   The last few runs of the Hr3 paint low clouds renaming for most of the day across far eastern OK, including the metro, and this would keep our temps in the upper 60s for highs.   Most data suggest any morning fog ( or mid-morning stratus) would break by midday allowing afternoon sunshine and highs either in the upper 70s or near 80.

The main forecast thoughts regarding the warm-up seem to remain in place for the next few days with above average temperatures for the next few days.    South to southwest winds at 10 to 25 mph will be possible Friday and Saturday with highs in the mid-80s.   A weak system (boundary) may near the area Saturday night into Sunday morning with very little impact on sensible weather.    Temperatures are expected to remain warm with lows in the lower 60s and highs in the lower 80s Monday and Tuesday.    A stronger surface low may develop across the northern third of the nation Sunday night and Monday allowing gusty south winds Monday from 20 to 35 mph across the southern and central plains.  

Most data support the potential for scattered showers and storms to develop either Wednesday or Thursday of next week as another storm system nears the southern plains.   Most data have been trending cooler for the end of next week.    But until then, it’s back to the warm air this weekend and early next week. 

Thanks for reading the Thursday morning weather discussion and blog.

Have a super great day!
