This somewhat unusual weather pattern that brought us a pleasant cool down yesterday with scattered storms across eastern Ok will remain through at least Tuesday, and possibly Wednesday, before the heat and humidity return for the second half of the week.
The large upper level low is now located west to southwest of the immediate area. We'll continue to have a shot at periodic showers and storms circulating around the main upper level low for the next 36 to 48 hours before the low weakens more as it slides westward. The coverage of thunderstorm activity today will be in the 40 to 50% range with highs in the lower to mid-80s. Locations southwest of Tulsa, including the central and southwestern parts of the state may stay in the upper 70s this afternoon. The area that received the most rainfall yesterday was central and western OK where 1 to 2 inches of rain occurred as temps remained in the upper 60s and lower70s for afternoon highs. The position of the low relative to eastern OK allowed for scattered thunderstorms Sunday afternoon with a number of locations again missing out on the precipitation.
The mid-level ridge of high pressure will build back into the area Wednesday morning to midday but we could still have a few storms Wednesday with some daytime heating. Just like yesterday, one or two storms may become severe with gusty winds and hail the main threat due to cold temps around 18,000 ft.
By the end of the week into the weekend, morning lows will move back into the mid-70s with highs in the mid-90s. Temp heat index values may reach 100 by Friday and Saturday.
The official high in Tulsa yesterday was 90.
The normal daily average high is 93 and the low is 73.
Our daily records include a high of 111 from 1936 and a low of 54 from 1967.
The precipitation for the year is now 15.60 compared to our normal precipitation to date of 22.87 which yields a deficit of -7.27 inches. These data do not contain any rainfall currently falling at 3:30am this morning.
