: Synopsis:

The trough that has brought precipitation to the region overnight into this morning (and a few lingering pockets of drizzle in north central MN) is transitioning to the north, while the next shortwave trough that will bring rain chances Wednesday is centered over Oregon upstream. After the next wave passes Wednesday a large upper low and persistent trough pattern is shown to remain entrenched upstream over the Pacific Northwest, with a general SW flow pattern across the central Rockies towards the Northern Plains. Our immediate region will tend to be under broader ridging within this split-southwest flow pattern initially keeping more active tracks and rain chances out of the region. However as the more active SW flow pattern builds east towards the weekend there are general rain chances which increase as the larger upper low/trough finally moves east of the Rockies into early next week. Current consensus keeps this to the south, however there is still a broad precipitation signal with this pattern change. Due to above average air mass remain in place there continues to be a signal/trend towards only rain.

: Rain on Wednesday:

The shortwave trough over Oregon quickly progresses across Rockies and into the Northern Plains overnight tonight into Wednesday morning and increasing forcing for ascent, moisture return, and some instability should support increasing rain coverage particularly in MN head of an associated frontal zone. There may be enough instability for some thunderstorm activity across west central MN which could contribute to localized higher rain totals. Strong/severe storms are not anticipated this far north with any potential for higher instability farther south. General totals will be lighter for most areas with probs for 0.1" and 0.25" high east of the RRV but probability in NBM/HREF for 0.5" lower (20-30% in our far east) and likely dependent on convective activity.

Conditions remain variable but a mostly a mix of MVFR to IFR with patchy LIFR lasting through 18z today. Some advection fog will exist across all sites (except KDVL) through 18z through likely 1-3sm at most times. Occasionally may dip below 1sm but not high enough confidence in when or where to put in the taf right now. Rain moving in the SW spreading NE from 12z to 00z with winds turning from southerly to westerly by 18z in eastern ND and all sites by the end of the period. Gusts briefly topping 20kts at DVL from 18z to 00z.
