Discussion

No appreciable changes will be made to the current forecast package with pattern continuing to feature a somewhat amplified upper flow. Guidance continues to show broad ridging over the majority of the nation with upper troughing / upper low now making its way on shore over the Pacific Northwest. This feature will become a major player in in the forecast early next week.

Satellite imagery continues to show a significant increase in moisture as southwest flow increases. Guidance remains steadfast in moving a couple of weak upper level impulses moving through and bring at least some showers and isolated thunderstorms to the state.

The first impulse is slated to move across tonight and early Saturday with the second one right on its heels keeping precip chances in the forecast through the weekend. The weekend will not be a complete washout by any stretch with QPF in the quarter to half inch range.

Weak ridging returns for Sunday night and Monday although a stray shower can not be ruled out. Attention will then turn to the previously mentioned west coast trough/upper low that will have moved from its current position and into the northern and central plains by the end of Monday.

Moisture levels will be increasing substantially as the parent low moves into the upper midwest Monday night into Tuesday. The surface cold front will be located over far east Oklahoma early Tuesday with a secondary area of low pressure developing along the boundary over far SW MO/far NW AR.

Long range models are in decent enough agreement with bringing the cold front through the FA Tuesday and Tuesday night with upper support keeping precipitation chances in the forecast Wednesday through Wednesday night. Rain will likely be in the region for election day but flooding is not a major concern with the speed of the system and antecedent conditions but several inches of rain can not be ruled out in spots and would actually be welcomed.

Severe weather at this time does not appear widespread with upper flow largely parallel to the system and stability looking limited. Still, a wary eye will remain on this system as it evolves over the next few days.

(12Z TAFS) Issued at 612 AM CDT Sat Oct 31 2026

Moisture levels will continue to increase as southwest flow aloft gets established. Widespread VFR conditions are expected initially before MVFR conditions start to develop later in the period. Showers and isolated thunderstorms will become common as the period progresses, especially towards the conclusion of this TAF cycle. IFR conditions will be possible Sunday morning. Surface winds will be predominately out of the southeast but start to shift more towards the west late but average under 10 knots.
