High pressure holds dry and warm weather into the first half of the weekend, although high clouds will increase and thicken. That occurs in advance of our first rain chance in awhile. The best chance of rain still looks to be between midnight Saturday night and midday Sunday, when the bulk of the 1/4 to 3/4 inches of cumulative rains should fall.

After this weekend, daily rain chances carry thru next week, with the best such chances Tuesday into Wednesday. That is when the bulk of the 3/4 to 1.5 inches cumulative rain falls over that time period, with some isolated higher totals upward to 2 inches possible farther west (Ozarks).

The onset of these rain chances means temperatures are driven back closer to seasonal norms with daily highs next week ranging from the upper half 60s to lower 70s. Adding to the more seasonal autumnal feel will be breezier winds with the aforementioned parent storm system's approach, arrival, and departure during the mid week period.

High-level clouds will thicken on Saturday as a storm system approaches the region. While VFR conditions will prevail, low cigs begin to build in from the west at the end of the TAF period as the column begins to saturate with increasing rain chances. Winds on Saturday will be ESE around 6-7 kts.
