Today just happens to be the date of our latest Spring freeze for here in Tulsa, a record set back in 1909. We were close to that this morning with a low of 37 and notice there were some locations right at freezing as the map on the right, courtesy of the OK Mesonet shows. So, after another very chilly start to our day, the sunny skies and lighter westerly winds will bring afternoon temperatures to at least near normal with mid 70s expected. Light winds and fair skies will make for a very pleasant evening, but southerly winds by morning should hold the overnight low into the upper 40s to start the day Saturday.
After that, much warmer conditions will be the rule as we go through the weekend and for the following week. In fact, all indications suggest we will see our first 90 degree weather by the time it is all said and done. Southerly winds will also be on the increase creating an enhanced fire danger. Temperatures Saturday afternoon are expected to be well into the 80s along with sunny skies and brisk southerly winds.
Sunday will be warmer yet with daytime highs expected to crack the 90 degree mark after starting off in the upper 50s that morning. Southerly winds up to 30 mph or so along with sunny skies and humidity levels dropping into the 20% range will also result in an enhanced fire danger situation.
Gusty southerly winds will also continue into next week with our nights reflecting the warmer, more humid air that those winds will bring with them. As a result, our overnight lows will be in the 60s, daytime highs in the upper 80s to near 90, and we will start to see an increase in cloud cover by Tue or Wed.
A few showers/storms may develop Wednesday, primarily for the western part of the state. Right now, the longer range guidance suggests better chances of showers/storms for our side of the state during the Thu/Fri/Sat time frame. Given that this is May, that will likely be accompanied by at least some severe storms, so advise keeping a close eye on weather developments later next week.
Notice the 7 day QPF map on the right which is valid through Friday morning of next week. This developing weather pattern will likely extend beyond that Friday morning time frame so we stand a decent chance of picking up some badly needed rainfall by then. Unfortunately, our neighbors out west will likely miss out of most of that.
So, stay tuned and check back for updates.
