- Showers and a few thunderstorms will develop from south to north today into tonight. Rain amounts from a quarter to around one inch are expected today through Thursday, with most falling through Wednesday. There is a 45 to 65 percent chance for amounts greater than an inch from the Brainerd Lakes into northwest Wisconsin and along the higher terrain of the North Shore. Chances for greater than an inch are less than 15 percent toward International Falls. A light wintry mix will also be possible tonight into Wednesday morning over parts of the North Shore.

Critical fire weather conditions will develop today over parts of northwest Wisconsin and far northern Minnesota. Strong low pressure was centered in western Nebraska as of 08Z and it's forecast to move northeast into southern Minnesota by 12Z Wednesday moving to near KGRB by 00Z Thursday. Winds will ramp up through the day today with a tightening pressure gradient and strong winds aloft moving in. 850MB winds of 50-60knots are forecast by the RAP by this afternoon/evening. Widespread gusts of 30 to 45 mph are expected with some even higher. The best overlap between the higher resolution models and NBM probabilities (60-90%) for gusts exceeding 45 mph is along the North Shore down into the Twin Ports. We issued a Wind Advisory for those areas this afternoon into the late evening. It's possible this advisory may have to be expanded. Occasional higher gusts will also occur with some of the showers as they develop.

Light showers were falling over far northern Minnesota early this morning and this activity is expected to push north over the next few hours. Area radars were also showing showers/thunderstorms over southwest Minnesota into South Dakota moving north. Just how quick this southern area moves north will play a role in fire weather conditions today. We expect a period of low humidity, 18 to 25 percent, and increasing winds with gusts of 30 to 40 mph for a time before the showers and increasing humidity move in. These conditions are most likely over much of northwest Wisconsin and far northern Minnesota.

Tonight and Wednesday...

A band of showers and a few thunderstorms will continue north tonight and strong winds will also continue. Localized even higher gusts will occur with the stronger showers. We expect a lull in coverage to develop behind the initial surge of showers/thunderstorms this evening with it filling back in as the upper low moves north. Surface temperatures may drop into the lower thirties along the higher terrain leading to a light wintry mix but any snow/ice amounts are expected to be quite light. Showers will remain likely for most of the Northland through Wednesday. 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. The highest chance, 45-65%, for amounts exceeding an inch will be from the Brainerd Lakes into northwest Wisconsin and along the North Shore.

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

Wednesday night through Friday...

Showers will diminish or end Wednesday night for most areas.
Colder air will move in behind the departing low and an upper trough will settle over the region Thursday. 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 and Sunday...

A drier period is expected with temperatures warming. Highs on Sunday will be in the fifties.

Issued at 1244 AM CDT Tue Apr 16 2024

VFR conditions will be occurring this morning with light showers in far north-central MN into the Arrowhead over the next several hours.
A strong low-level jet associated with approaching low pressure is expected to produce LLWS for several terminals, including HIB, BRD, and HYR. BRD will see low-level wind shear begin as early as this morning, while LLWS won't be ramping up in HIB and HYR until the late afternoon into early evening today. Widespread rain will be moving from southwest to northeast across the region through today.
MVFR and eventually IFR cigs are likely to occur this afternoon and evening as the low pressure moves further into the area. Expect strong east to northeast winds through much of the TAF period due to the arriving low pressure system.

Issued at 346 AM CDT Tue Apr 16 2024

Easterly winds will be on the increase today into tonight with widespread gales developing. As low pressure lifts northeast today into tonight, strong winds will develop with gusts of 30 to around 45 knots expected. The strongest wind will occur this afternoon into late evening. Gale Warnings are in effect for most of the nearshore waters with Small Craft Advisories for the remaining areas. 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 will develop late today into tonight and continue Wednesday.

Winds will become westerly Wednesday night and decrease further.
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.
