Frost Advisory Tuesday Night


The National Weather Service has issued a Frost Advisory (lighter blue) for parts of east central Minnesota into western Wisconsin Tuesday Night. Temperatures are expected to get down into the low and mid 30s for lows by daybreak Wednesday.


Meteor In The Northeast

Credit: Burlington Airport

Those who were up late enough Monday Night (around 12:50 AM ET) in parts of the Northeast were lucky enough to catch a spectacular meteor streak across the sky! Three different security cameras at the Burlington, VT airport caught the fireball as it flew through the night sky. It was a very photogenic meteor, as dashboard cams from the Portland, ME and Plattsburgh, NY Police Department also caught the very bright meteor on camera.

Wet Spring So Far... For Some

After a wet week last week, with four out of the five weekdays recording rainfall in the Twin Cities, I figured it was time to pull out the precipitation map for spring (since March 1st) so far. There have been a couple clear areas of wet weather this spring where precipitation is above average - one in southwest Minnesota (where some areas are a good 1-3" above average according to the Midwest Regional Climate Center) and another across much of northeast Minnesota. In fact, the 5.20" of rain in International Falls makes it the 13th wettest first 77 days of spring in history. Meanwhile, if you head out to northwest and west central Minnesota that's where you find the driest weather over the past two and a half months. St. Cloud is 1.63" below average for this time of spring.


Minnesota Crop Update


The USDA and the Minnesota Department of Agriculture issued its weekly crop update Monday for the state of Minnesota. While most crops are ahead of schedule (versus the five year average) when it comes to planting, including corn, last week only provided an average of 2.3 days suitable for work in the fields. That was even less in southern Minnesota due to continued precipitation. There is also concern about how the frost/freeze last weekend may have affected development - potentially even causing damage. Read more from the USDA here.

The good news, according to University of Minnesota Extension corn specialist Jeff Coulter, is that while there may be injury to the corn from the frost, it shouldn't have killed the corn: "The growing point on corn seedlings is currently about 0.75 inches below the soil surface and remains below the soil until the five to six leaf-collar stage. Therefore, frost prior to the five to six leaf-collar stage typically does not kill corn unless prolonged cold temperatures freeze the upper part of the soil where the growing point is located."

Meanwhile, the grape crop at the Wollersheim Winery in Wisconsin took the worse hit they've had in about three decades. More from KARE-11: "Head winemaker Philippe Coquard says the temperature dropped to 27 degrees early Sunday and despite the heating equipment used to save the grape crop, the entire 32-acre vineyard at Prairie du Sac was damaged. Coquard says 75 percent of the red grapes have been lost and 25 percent of the white grapes."

A Week of Weather Destined to Daze and Amaze
By: Paul Douglas

Dear Diary: there was this one week in mid-May, 2016 where I ran out of things to talk about. I remember that week fondly. Falling off of my weather-hammock (repeatedly). Painting graffiti on the Doppler. Posting cat videos and hair-care suggestions on my weather blog. I distinctly remember San Diego calling. They wanted their weather back.
Minnesota experiences some of the most extreme weather on the planet (what's 130 degrees among friends?) so we can all be excused for gloating about a miraculous stretch of blue sky, fair weather cumulus and lukewarm breezes. Best of all: our high pressure hallucination lingers into the weekend as winds turn to the south, warming us to 80F by Sunday. Only in Minnesota is it even possible to go from flurries, frost and wind chill to 80F in the span of a week.
Studying the models I don't see a drop of rain until late Monday, when a fizzling frontal passage may spark a few thunderstorms.
Until then the lights are on, the weather center is still open for business. But I'll be swinging on my hammock, thanking the Good Lord for a break.

Wednesday Minnesota Weather Outlook
Temperatures will climb into the upper 60s to low 70s across much of the state of Minnesota on Wednesday. With a forecast high of 70, today will be the first day we will see a high that is back at (or above) average since the 9th of this month! If you want cooler weather, well, you just got to be by the lake as a southerly wind off Lake Superior will keep areas like Duluth and Grand Marais only in the 50s.
A mix of clouds and sun will take us through the day Wednesday across the state with no real precipitation in sight.
In fact, it's going to be a fairly dry week across the state, with the next chance of rain (maybe even a few thunderstorms) not moving into the region until early next week. Enjoy the nice weather the next few days, as there are areas of the county expected to see a good 2-4"+ of rain over the next several days.
National Forecast Outlook

The storm track will remain south of Minnesota as we work through the rest of the week. A frontal system sagging southward will be a focus for the potential of heavy rain across portions of the southern and eastern U.S. over the next few days. Also, as we head into Thursday and the end of the week, we'll watch a cut off low move south over the northwest U.S. that will bring them an extended period of showers and storms.

Rainfall potential through Saturday. Green = 1"+, yellow = 2"+, orange = 3"+, red = 4"+.
With round after round of storms expected across parts of the southern U.S., rain totals have the potential to quickly climb this week. Across portions of the south, atmospheric moisture values are expected to be between one and two standard deviations above normal for this time of year. What that means is that heavy rain can be expected in places, with some easily picking up another 2-4"+ through the end of the week.
Snowfall potential through Thursday. Blues indicated totals between 1-6", yellow 6"+.
In parts of the western mountains, we are still talking about winter weather. Through Wednesday evening, 3-10" of snow could fall in parts of Colorado, with 1-2 feet possible for Pikes Peak. Luckily we aren't dealing with that here!
The previous wettest day in Vero Beach, FL history was January 21, 1957 when 8.82" of rain fell.

Thanks for checking in and have a great Wednesday! Don't forget you can follow me on Twitter (@dkayserwx) or on Facebook (Meteorologist D.J. Kayser)!
