- There is a medium chance for scattered weak thunderstorms Friday afternoon. Main hazard would be lightning.

...Synopsis...

Blocked upper ridging remains over the central CONUS, with upper troughing over the West Coast. This upper ridging is driving well above average temperatures in the 70s currently over the region. Weak embedded impulse moving through the flow is utilizing weak instability aloft, helping spark scattered rain/virga showers in northeast ND and northwest MN this afternoon into evening. Dry air in the lower levels will prevent much of this precipitation from reaching the ground, thus added sprinkles to the forecast to account for this.

On Friday, well above average temperatures will occur once more with widespread 70s forecast during the day. While temperatures will be mild, gusty southerly winds 20-40 mph will also build starting Friday by late morning, lasting through the day.

Upper trough in the West will attempt to break eastward, although all guidance suggests this will occur in a split-flow- like regime, with the northern branch of the upper trough in northern CONUS and Canada separating from the southern branch lingering in the Southwest. As it does this, it brings sufficient moisture and lift to bring scattered showers Friday afternoon into evening. Most guidance also indicates at sufficient instability aloft to bring lightning/thunderstorms into the conversation. A lack of better instability, moisture, and wind shear spacing will mitigate how strong thunderstorms will be - likely keeping storms weak.

Strong cold front moves through Friday night into Saturday driven by the northern branch of the upper trough. This ends our well above average temperatures, with most locations seeing daily high temperatures Saturday occur just ahead of this cold front, occurring early morning Saturday.

Medium to high confidence in VFR conditions throughout the TAF period. Winds are forecast to remain out of the south to southeast generally around 5-10kt before 12Z. After 12Z, winds increase 15-25kt, gusting near 30kt in southeast ND and west- central MN, including KFAR, particularly late in the morning through afternoon. There is a medium chance winds reach 30kt at KGFK as well during this same timeframe.

Virga/light rain showers are forecast this afternoon into tonight in northeast ND and northwest MN. Additionally, there is a low to medium chance for showers and weak thunderstorms are Friday afternoon into early evening in portions of the Red River Valley into Minnesota. Confidence is not high enough to include this in any TAFs at this time (PoPs around 20 percent).

One note on observations at airport sites - reduced visibility and HZ reported at some TAF sites are likely resultant from nearby agricultural activity kicking up dust and dirt. Because of this, we are opting to not include within TAFs.
