1/31/09: Saturday's Weather Report

Issued at 4:30 PM CST, Saturday, January 31st, 2009

Surface Analysis at 22z:

Low pressure averaging 982 mb was moving into the Southwest half of Ontario. A warm front attached to this low had lifted into far Northeast Minnesota with a cold front attached to this low just entering far Northwest Minnesota. A prefrontal trough or wind shift line was noted over Central Minnesota. Strong pressure rises of 2-3 mb per 2 hours were occurring This Afternoon behind the trough and cold front and on the southwest side of the deep low off to our north.

The January thaw came in with a vengenance around Minnesota Today as high temperatures soared through the 30s and 40s with even a few locations out West inching close to the 50 degree mark! The 60 and 70 degree temperature contours came as far north as far Southern Nebraska and far Southern Iowa Today. Strong warm advection partially responsible in causing these very warm temps around Minnesota Today was shifting east of the state as of late Today…

1/31/09: Incredible warmth/powerful storm

Issued at 12:50 PM CST, Saturday, January 31st, 2009

At 1830z a deep area of low pressure averaging 984 mb was centered over Eastern Manitoba with strong darkening noted on water vapor satellite imagery surging southeast across the Northeast half of North Dakota into Northwest Minnesota. This powerful low is causing temperatures to sky rocket over all but Northern and Northeast Minnesota early This Afternoon in addition to this, high winds were spreading through North Dakota and will soon move into Western Minnesota. *Note: 51 mph wind gust recently at Crookston Minnesota per 1 PM observation.

*High Wind Warning* is in effect through 6 PM CST Today for far Western Minnesota with a *Wind Advisory* in effect from 6 PM This Evening until Midnight CST Tonight for this same area. Some cities included in these headlines are... Crookston... Moorhead... Hallock... Warren... And Breckenridge.

1/30/09: Friday's Weather Report

Issued at 3:12 PM CST, Friday, January 30th, 2009

If the high temperature fails to reach 32 degrees at Duluth on Saturday, then this will go down as just the 15th time since 1874 that a January has failed to produce a temperature of 32 degrees. It's a tricky forecast for the city on Saturday, we have pros and cons at the present time. One thing favorable for temps reaching or even exceeding 32 degrees is that will have a southwest to west surface wind, plus a deep surface low will be passing by to our north putting us in the warm sector for a time. Negatives would include the deep snow cover and the fact that we may be dealing with a temperature inversion with warm air aloft and cooler air trapped at the surface, but if the strong winds aloft can mix down to the surface, then this inversion will break up enough allowing for sunshine to develop which would aid in warming things up and causing the mercury to possibly reach the freezing mark for the first time this month. The last…

Upper Air Analysis at 22z:

Northwest flow aloft has amplified a bit Today around the Upper Midwest as a new surge of arctic air spreads south into Minnesota behind the weak system that moved through last night. An upper level trough was seen on water vapor satellite imagery progressing east across the Upper Midwest and Upper Great Lakes Today with a few disturbances rotating south-southeast along and behind this upper trough. A 120-140 knot jet max was found from Central Saskatchewan Province through Eastern Montana and the W…

1/26/09: Monday's Weather Report

Issued at 4:07 PM CST, Monday, January 26th, 2009



Weather History:



On this date in 2004, 0.78" of precipitation and 18.2" of snow fell at Duluth Minnesota.



Weather Tidbits:



As of Today's date, the entire Western portion of Lake Superior has frozen over based on satellite imagery. This was about the sametime that Western Lake Superior frozed over back in 1994. While in 1977, Western Lake Superior frozed over about a week earlier. Both 1994 and 1977 were memorable winters around the Great Lakes.



Average Temperature at Duluth Minnesota from December 27th through January 25th has been zero degrees and this has been 7 to 8 degrees below what the mean temperature should be during this time period.



Precipitation Total at Duluth Minnesota from December 27th through January 25th has been 0.50" which is just 25-50% of average for this time period.



In other words, it's been very cold and extremely dry for the most part since late December.
