The first round of showers and storms moved across the area yesterday with pockets of moderate to heavy rainfall mostly across the southeastern quadrant of the region. The main upper level system will continue to be near the area for another 30 hours or so with additional showers and storms possible for some locations. Pockets of heavy rainfall can’t be ruled out in a few spots and our friends at the National Weather Service will issue a flood watch for eastern Oklahoma. Additional rainfall from 2 to 3 inches will be possible atop the totals from yesterday. This could bring three-day totals between 1 to 4 inches in some locations with a few outlying higher amounts. The severe weather threat, just like yesterday, will remain very low but not totally zero. The main upper level low will be ejecting across the area tonight into pre-dawn Wednesday and could result a few strong to severe storms. This threat will remain very low.
The main upper level low has been cut-off from the upper air flow for the past few days but will be ejecting to the northeast by Wednesday morning. The upper air flow will transition once again to a northwest flow aloft Thursday into the weekend with several chances remaining for showers and storms near the region. At first glance, we’ll have slightly higher chances in the extended Friday morning with some chances both weekend mornings. A front will move across the area Sunday night into Monday morning with another slightly higher chance for northern Oklahoma.
The rain chances today will again be spotty at times but will require high chances to cover different parts of the day and evening. The better coverage this morning may end up to the east or southeast of the metro, yet some activity is likely to skirt the Tulsa region for a few hours this morning. We’ll more than likely experience a relative lull in the precip around midday with a few storms developing again by early afternoon. Finally, later tonight, additional showers and storms are likely as the main system ejects northeast and a surface front enters the area. This system will move across the area tonight and exit early Wednesday morning.
Temps remained well below average yesterday with highs in the upper 70s and lower 80s. Today’s afternoon readings should move into the mid-80s with temperatures gradually increasing for the remainder of the week. Thursday will feature highs in the lower 90s and Friday will be the warmest day of the week with highs nearing 93. Tropical like moisture will remain with heat index values nearing 100.
The potential for additional showers and storms this weekend should act to keep the highs back into the upper 80s near 90 for weekend afternoon temperatures with morning lows reaming in the upper 60s to lower 70s for the next several days.
Thanks for reading the Tuesday morning weather discussion and blog.
