Another day of a few scattered storms producing heavy rainfall will be possible along with highs in the lower 90s. The tropical-like air characterized by lower to mid-70 degree dew point temperatures will keep the muggy weather centered over the state but will also fuel storms allowing for efficient rainfall production. Daytime highs in the lower 90s will be likely today along with south winds near 10 mph. No significant focus for storm activity is found across the eastern sections today but residual outflows from last night may help to trigger a few storms today into this afternoon. There is a weak boundary also to the south across southern OK this morning that may also activate later today.
The upper air flow from the northwest will become stronger Thursday through Saturday morning and should allow a storm complex (or two) moving from the northwest to the southeast across the area. The exact timing and trajectory remains uncertain but seems to be suggesting Thursday night into Friday morning and possibly Friday night into Saturday morning. The presence of the low level moisture and the enhanced upper air flow will support a severe weather threat with storms capable of producing damaging winds for a few locations but at this point, widespread severe weather is unlikely to occur.
Saturday afternoon into Sunday most data support the mid-level ridge of high pressure to expand east and slowly gain strength into next week. This should effectively shut down the storm chances for many locations and bring the heat back to the region. Unfortunately the air mass will remain intact and heat index values will more than likely exceed 105 next week.
Temperatures will remain in the mid-70s for morning lows and in the lower 90s for daytime highs for the next three days before rising a few degrees Saturday and Sunday.
Thanks for reading the Wednesday morning weather discussion and blog.
Have a super great day!
