More Sun, Less Humidity
Showers tapered off Tuesday evening, and drier air started moving in behind a cool front. It is taking a while to feel that change, though! Temperatures should drop into the middle 40s in most communities around here by sunrise, and the air warms into the low-70s (upper 60s in the higher elevations) by mid-afternoon with a full complement of sunshine and low humidity on Wednesday.
Sure, temperatures will run a touch below normal on Wednesday and Wednesday night, but we warm up and bring back thick humidity by the weekend and first part of next week. There's also quite a bit of rain in the forecast through next Tuesday and Wednesday!
Warmer Days and Some Rain: The cool air mass in place is driven by a strong surface high just north of us on Wednesday; that high’s influence is strong enough for one more chilly, dry night. Low temperatures range from 40 to 45 degrees by Thursday morning.
The high loses influence by Thursday afternoon, and a wind shift (coming from the south-southeast) helps warm us up into the upper 70s and lower 80s. Clouds increase Thursday evening ahead of another cool front; that system brings another chance of scattered showers and a few thunderstorms Thursday night into Friday morning. Rain could start as early as 9-11 PM and last through sunrise. No widespread severe weather is expected, but some storms may be a little strong with some gusty winds and heavy rain.
That wet weather clears out on Friday morning leaving us warm and dry in the afternoon: look for a sunny sky with a high around 78 degrees.
Weekend Update: The weekend looks fair and warm, but there will be a chance of some scattered showers both days. Friday’s cool front stalls south of us on Saturday and lifts north (slowly) through Sunday. As that happens, clouds and a few showers will be a possibility; however, a plan-canceling kind of rain is not likely. Expect highs in the low-80s.
Rain and Storms to Start Next Week: A potent, slow-moving storm system brings a chance of some heavy rain and potentially some strong or severe storms on Monday and Tuesday. Rainfall estimates from Sunday night to Wednesday are impressive: somewhere in the neighborhood of 2 to 5 inches.
Severe Weather Potential: The early-week storm system looks ugly to our west. The Storm Prediction Center has already outlined a severe weather "threat" area in the Plains for the weekend (Texas, Oklahoma, Arkansas, and Missouri in particular). There may be a threat of some strong or severe storms around here on Monday as that system advanced east; it's still too early to see specifics, but the trend in the guidance gives us a feeling that we will need to be on guard for some stormy weather come Monday.
