KEY MESSAGES

- Rain comes to an end this evening, with patchy fog and drizzle overnight.

..Rain Today, Fog/Drizzle Tonight

Rain is slowly ending from west to east across southern reaches of the FA. In its wake, several observation sites are reporting drizzle. Soundings show saturation up to 2 Km in depth persisting into tonight with sufficient low level lift. Therefore, patches of drizzle and fog will remain a concern into Saturday morning. It is uncertain when stratus and drizzle will burn off Saturday morning, as for the most persistent locations (which are currently favored to be in far southeastern ND), it may take until the drier air behind the cold front comes through during the afternoon hours.

AVIATION /18Z TAFS THROUGH 18Z SATURDAY/

Issued at 1235 PM CDT Fri Sep 18 2026

The main concern today into tonight will be the expansion of MVFR to IFR ceilings. MVFR is already impacting KDVL and KFAR. This will continue throughout the afternoon hours. By late afternoon into the evening, MVFR will expand northward into all remaining terminals, eventually turning into IFR. IFR will persist into Saturday morning. A few gusts of up to 20 knots are possible this afternoon. Once clouds set in and the sun sets, winds will decrease substantially overnight, becoming variable at under 5 knots. Fog and drizzle may also develop as ceilings lower overnight, but predictability in these hazards remains low at this time for any one terminal.
