/Issued 6:15 PM CDT, Thursday, July 12, 2018/
Summer of 2018 will be remembered as the summer that produced multiple flood events in the Northland, and we’re only going into mid July! Still lots of summer left.
One-minute Goes16 visible satellite loop from 3:54 PM to 5:35 PM, Thursday, July 12, 2018. Watch thunderstorms explode late this afternoon over southern and eastern Minnesota and western Wisconsin, cloud tops of 50,000 to nearly 60,000 feet with these storms!
12z GEFS model (7.12.2018)
500mb height anomaly forecast valid through July 28, 2018 — Will start with a westerly flow aloft but transition to more of a northwest flow aloft across the upper Midwest by next week and beyond, this will likely lead to temperatures that are near or below average from mid to late month. Core of the heat will be over the southwest U.S. as persistent ridging continues in that area through at least the next two weeks.

A wild early morning in parts of the area as strong to severe thunderstorms moved south/east bringing torrential rainfall rates which led to flash flooding — The hardest hit area, well two areas actually…The first was over a portion of far northern Minnesota around the Cook area, the other more widespread area impacted southwest portions of the Northland around the Brainerd Lakes to Aitkin, Hinckley, Mille Lacs Lake and Mora areas. Rainfall totals of 2 to around 5 inches fell in a short period of time which led to flash flooding. Thunderstorms earlier today also produced tremendous amounts of lightning, with at least one lightning strike starting a church on fire just after 5 AM today in the Piedmont neighborhood of Duluth.
Late this afternoon finds a cold front draped from southern Minnesota to north central Wisconsin with severe thunderstorms firing up near this boundary as of 5 PM. Farther north in our area skies which were overcast earlier in the day turned partly to mostly sunny this afternoon. Highs today ranging from around 80 to the middle 80s with dew points in the lower 70s in northwest Wisconsin with 50s in parts of northern Minnesota.
Partly to mostly cloudy skies for tonight with a risk for a few showers or thunderstorms mainly in southern portions of the Northland. Lows will be in the mid 50s to upper 60s.
Friday and Saturday look mainly dry in our area with some sun expected both days. Highs in the 80s, with dew points in the mid 50s to mid 60s, so still a touch muggy but not terribly muggy.
High pressure moves east out of the northern Plains tonight, passes over the upper Midwest Friday before moving off to the south/east on Saturday. Behind this high will be the next cold front which is set to move through the area late this weekend with isolated to scattered coverage of showers and thunderstorms possible on Sunday the way it looks now.
Forecast for Duluth and Superior
