As predicted we’ve had a great July rain wise for the majority of the state. Just take a look at the last 30 days:
Rainfall totals for July.
This places a large area of the state above normal during this period with the exception of the south:
Percentage of normal rainfall.
Finally, although we saw a few 100s officially in OKC and Tulsa (3 days in each), it hasn’t been too bad heat wise either. A lot of the days over 100 on this map also occurred prior to this month in NW OK:
Days at or above 100 degrees this year.
So here’s both the short-term and long range forecast update going forward:
Additional scattered showers and storms should form late this afternoon across the state. Highest concentration will be from the OKC metro area E and NE to Tulsa. As you know, these typically mean heavy downpours leading to temporary flooding and accompanied with lightning. Sometimes they contain damaging microburst winds when the storm cells collapse.
Also, a cluster of storms called an MCS (Mesoscale Convective System) will roll through E CO W KS and into NW OK before dissipating overnight. This is caused by a change in the jetstream pattern to a NW flow. The mesohigh that moves in will help to keep temperatures a little cooler for our Friday. Another round will develop Friday night and Saturday morning off of this residual boundary once again helping to shave a few degrees off the heat.
Not much is expected rain wise on Sunday. Maybe a few storms across the N half of OK but otherwise the heat builds back in a bit more as we lose the NW flow and replace it with a ridge of high pressure overhead. This leads us back into the pattern of mostly and hot days with temperatures in the upper 90s to a few 100s. Although it may take awhile to dry out the recent ground to hit those high marks across C OK, but it will definitely feel like an outdoor sauna!
Super long range outlook has the NW flow returning around the 10th to the 15th of August which should bring a little rain with it, then back to the upper ridge for the rest of the month. Temperatures should be just about normal for August.
