DISCUSSION
Issued at 402 PM CDT Tue Apr 16 2024

Things are getting quite interesting out there this afternoon, with rain spreading in from the south with a little embedded thunder in it. As the rain moves in, the winds increase, with gusts beginning to push into the 40 mph range, with a few places around the Twin Ports even stronger than that. Before the rain moves in, RH values have dropped into the 15 to 25 percent range, which then rapidly rises as rain moves into the immediate area. Expect this trend to continue as the rain pushes north through the evening. This precipitation should be all rain, but due to the dry lower layers, there may be a brief period of snow before RH values increase and the precip stays all rain. The band of heavier precipitation over central MN will also push north this evening, forced by the mid level frontogenesis and the plume of strong moisture advection and isentropic lift that pushes north across the forecast area tonight. We should get an area of lighter precipitation behind this initial surge of rain, followed by another heavier band closer to the mid level low center, which then moves across the area during the day on Wednesday. Surface temperatures may drop into the lower thirties along the higher terrain leading to a wintry mix but any accumulations should not be significant. PWAT values are still forecast to be from 0.75 to 1". These values remain in the 90th percentile which is high but not extreme. Rainfall amounts today through Wednesday are expected to range from around a quarter inch to around an inch, though there may be some locally higher amounts along the North Shore and parts of northwest Wisconsin.

The wind will be diminishing from west to east tonight and through the day Wednesday.

Thursday through Friday...

Colder air will move in behind the departing low, leaving a trough extending back across the region Thursday and Friday.
There will be chances, 20-60%, for showers Thursday into Friday (lowest south and highest north toward the International Border). The precipitation will mix with or change to snow during the overnight/morning periods but any snow accumulation will be light. Friday will be the coolest day of the period with highs from the upper thirties to mid-forties. It will also be windy Friday with west or northwest winds gusting to 30 to 35 mph.

Saturday into early next week...

A drier period is expected with temperatures warming. Highs by Sunday will be in the fifties, continuing into early next week.
There is some potential for another round of precipitation early next week, but model agreement is very low, ensemble spread is high, and do not have much confidence in it.

AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/
Issued at 1243 PM CDT Tue Apr 16 2024

Difficult flying weather for this TAF period. All the terminals were VFR as of issuance time, with rain just beginning at KBRD.
Conditions to gradually deteriorate over the next 12 hours, with ceilings gradually dropping to at least MVFR by 06z tonight, then lower still to IFR for some sites by 09z, with the lowering conditions spreading from southwest to northeast with the incoming rainfall. Visibilities are also expected to lower to MVFR as the rain moves in. Once conditions get to IFR, I expect most sites to remain IFR through the end of the TAF period, though we may get some visibility improvements as breaks in the precipitation begin to work in. Wind is a fairly significant concern, with winds continuing to increase this afternoon, sustaining in the 15-25knot range with gusts over 30kts for most of the terminals between 22z and 06z, with winds beginning to weaken after than, and then backing into the north and weakening still further after 12z.

MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/
Issued at 402 PM CDT Tue Apr 16 2024

Increasing east winds over western Lake Superior are leading to widespread gales and flirting with storm force gusts over the Twin Ports. As winds are expected to increase with gusts up to 50 kts this evening, a Storm Warning was issued across the Twin Ports.
Tonight, winds will decrease slightly, and only gales will be expected at the head of the lake. Gale Warnings are in effect for most of the remaining nearshore waters with Small Craft Advisories for Saxon Harbor to Chequamegon Bay. The wind will gradually back through the day Wednesday to northeast and decrease some but conditions will remain hazardous. A period of showers and perhaps a few thunderstorms are moving to over the lake this afternoon and will continue tonight and Wednesday.

However, this will be short-lived and west to southwest winds will increase again Thursday creating hazardous conditions, especially for smaller vessels. Strong winds will continue into Friday.
