UPDATE

Issued at 537 AM CST Thu Dec 26 2024

Based on latest MN DOT RWIS observations and other sources, did remove any chance of light freezing drizzle from the fcst. RWIS vsbys 5 miles or greater in MN, at all but one site which was under 2SM. Similarly in E ND low clouds continue with a slow clearing progress ENE...a bit faster north vs south. Backedge of clouds Cavalier-Lakota-Jamestown ND. in RRV cigs under 1k ft agl but vsbys 5 miles or greater. Did also remove fog after early morning for many areas as looks like fog shouldnt be an issue today with light fog and vsbys generally 5sm or P6SM.

..Next week.

Overall next week will feature a cooling pattern, esp after Jan 1st, as temps return to more normal values. No signifcant precipitation is anticipated.

AVIATION /12Z TAFS THROUGH 12Z FRIDAY/

Issued at 537 AM CST Thu Dec 26 2024

Fog not present nearly as much as past nights. Low clouds continue with ceilings 300 to 700 ft in much of far E ND into MN. Tricky part will be how far east does clearing get today. Using 925 mb RH progs looks like enough of a WSW wind at this layer to bring brief clearing into GFK vs not at Fargo or TVF/BJI. Devils Lake should remain scattered clouds thru the daytime. South winds still gusting over 20 kts in the RRV but overall a slow downward trend today. Tonight is likely to see an increase in low level moisture so that any site that does get rid of low clouds will see them return. Fog may reduce vsbys into IFR range late tonight.
