July 2020 - General Weather Discussion

[mugofbeer]

Difficult to forecast MCSes coming down from CO/KS. Saturday was a boundary draped across N OK, with storms riding their outflows.

We could see another rogue MCS tonight and even Tuesday night. However, the forecast right now is for these to die before reaching main part of OK. (We shall see)


Otherwise extremely hot pattern continues through weekend, with relief in sight around Sunday-Monday with some higher rain chances and cooler weather.

Your storms have come up along the Colorado front range of the Rockies or jumped the I25 corridor and exploded on the east plains and held through the night into OK. These haven't been monsoon storms but those are supposed to start tomorrow. Storm systems could continue to be a nightly thing for KS and OK for a while.

Break from the near 100s is on schedule for this week. Slight chances at some random storms Monday night and perhaps Tuesday night. Best shot is northern OK, but all areas chances are low.

We will look into the GOM by end of this week for potential development.

Ahhh... Got a nice shower; about .25" near Penn Square.

And temp dropped down into the 70s.

Ahhh... Got a nice shower; about .25" near Penn Square.

And temp dropped down into the 70s.

We’ve been hearing a lot of thunder to our east.

Tropical moisture continues to flow into the area due to the storm down in the GOM.

Slight chance of random pop up storms this afternoon, enjoy if you're lucky enough to be under one.

Stalled out boundary across the area and a dead tropical storm getting shredded across Central America will result in good rain chances this week. Beginning this afternoon, we should have major rainfall events across large portion of the state.

First round is developing now across N OK and will continue to sag south and east throughout the day. Afternoon will flair up with showers and storms across I-44 corridor. Another heavy round expected late Tuesday morning into afternoon. And repeating again Wednesday. Then it looks like a chance of a line of storms late Thursday into Friday.

Timing of everything is still pretty tough to forecast, so just check radar before doing any outdoor things.


Exact placement of heaviest rain is pretty hard to pin-point, but models favoring C and SC OK. Localized areas of 4"+ and general swaths of 1-2" is likely.

I guess we need the rain

[mugofbeer]

It's a very fortunate event considering it should be dry and in the mid to upper 90's in OK right now. You're stealing CO's monsoon!

[SoonersFan12]

At least it did not flood

[Anonymous.]

As of about 20 min before modnight - Western sides of the metro will be seeing flashflooding at the rate the storms are increasing over the area. These storms will continue to meander with little to no direction. Results will be extremely localized flash flooding.

[Anonymous.]

Models develop another cluster of storms heading into tonight across the area. Again, local flash flooding is main threat.
