Rain Chances Soon

Good morning. We're beginning to move into an active weather pattern for the next few days as the southern stream sends a few waves across the southern plains.   The first minor impact is underway this morning with some drizzle and light showers attempting to develop across part of far southeastern OK and north TX as warm moist air moves northward up and over a warm front located across part of Texas. There will remain a very slight chance of some drizzle or patchy fog developing as the day progresses across portions of eastern OK but the overall chance will remain low.

The main upper level wave of interest is located near the West Coast this morning and will begin moving eastward later today and tonight.   A few sprinkles or showers will be possible Thursday with higher rain chances arriving Thursday night into Friday morning across central and eastern OK.   This wave will exit the state Friday midday to early afternoon with the rain ending from the west to east by midday to late afternoon.

The next wave appears to be nearing the state Saturday night into Sunday, but the latest model output continues suggesting a southern route. This would take the higher rain and thunderstorm chances across North Texas and the Red River Valley of southern OK.   We'll continue to keep a very low chance for some showers Sunday, but the chance will remain about 10%.

Temperatures for this forecast cycle will remain near or below the seasonal average. Afternoon highs today will remain around the mid or upper 40s with mostly cloudy conditions and winds from the northeast at 10 mph.   I should make note, that even a few breaks in the clouds this afternoon would allow temps to move into the lower 50s, but we're counting on the cloudy conditions to hold for the day.   Thursday morning lows should be around 40 with afternoon highs in the lower to mid-50s followed by Friday highs nearing 57 to 61.

The weekend will remain cool with morning lows in the 40s and afternoon highs in the upper 40s to 50 Saturday, and into the lower 50s Sunday afternoon.   The EURO data has now come around to a “ less cool” solution, but does offer a minor cool down for Tuesday.   Once again, I'll offer a compromise blend with a nod toward the EURO.

Thanks for reading the Wednesday Morning weather discussion and blog.

Have a great day!
