-Second coldest low temperature on record at International Falls, Minnesota this morning, Friday, July 14, 2017 -- Low temperature was 39 degrees. The coldest low temperature on record for July 14 is 38 degrees set in 1960. Note: Records date back to 1895.
A much nicer day across the area under mainly sunny skies this afternoon. Highs today were in the 70s with International Falls close to 80 degrees (3 PM) Note: Temperature climbed ~40 degrees at International Falls Today with the morning low of 39 F, and the afternoon high of 78 F.
Tonight: Clear to partly cloudy through the evening and partly to mostly cloudy overnight. A warm front and cold front over the northern Plains late this afternoon will head east/southeast reaching western/northern sections of Minnesota by daybreak. A warm air advection pattern will occur ahead of this system tonight with a gradual uptick in elevated instability during the night as CAPE values climb to 500-1500 j/kg. Isolated showers or thunderstorms are possible tonight in parts of the Northland but most of us should stay dry. Not as chilly tonight as last night with lows tonight in the 50s to low/mid 60s.
Saturday: A cold front is forecast to move southeast through the Northland by early afternoon -- Warm and humid along and ahead of this front with less humid conditions behind it. There will be plenty of instability, moisture and wind shear present for strong to severe thunderstorms Saturday, but right now it doesn't look very likely that thunderstorms will form as this front moves through our area. Still can't rule out isolated coverage of showers/thunderstorms Saturday, but most of us like tonight should stay dry. Highs Saturday in the upper 70s to upper 80s with the warmest temperatures in east central Minnesota into northwest Wisconsin. It will be muggy Saturday with dew points from 63 to around 70 degrees along and south of Highway 2 in northeast Minnesota including over all of northwest Wisconsin while it will be less humid in northern Minnesota with dew points generally around 60 degrees.
Sunday: Lake wind develops resulting in cooler/less humid conditions near Lake Superior with highs mainly in the 60s. Milder inland with highs in the 70s.
Monday: Warmer and turning more humid as winds turn to the south. Showers and thunderstorms are possible at times, and a few of these storms could become strong to severe. Highs Monday in the 70s and 80s, cooler near Lake Superior. Dew points are forecast to climb into the 60s to lower 70s.
