Day 12 of Tulsa, OK (KTUL)

Clearing skies and cold advection, but with winds too strong for good radiational cooling, led to a low of 47F. Mostly sunny skies led to a gradual warmup to 66F, with the sunshine helping to mix down stronger winds from aloft, especially earlier in the day when the pressure gradient was stronger and when the maximum wind of 19 kt occurred. Cloud cover is quite uncertain tonight, leading to an uncertain low temperature. Some high-level clouds may be present, but they will mostly be gone after this evening. However, low and mid-level clouds will expand slightly from the south, but could break up as they approach Tulsa, or reach Tulsa and then break apart before sunrise. Radiational cooling will get going somewhat during clearer periods, but northeasterly winds will be slightly too strong for ideal radiational cooling, though perhaps a bit weaker than last night and still helping to advect cooler air in. With partly to mostly sunny skies early in the day tomorrow, there will be a decent warmup before thickening mid and high-level clouds along with continued modest cold advection stop the warmup, making it slightly cooler than today. Any sunshine will help mix down stronger winds aloft down to the surface, leading to a similar or slightly lower maximum wind to today. There is the chance of a shower tomorrow evening, though with rather weak forcing for precipitation and most of the moisture going to the south, the dry low-level air will likely evaporate the rain before it reaches the ground.
