Weak area of low pressure will be over western Minnesota tonight with a cold front also over western and extreme northern Minnesota.  Partly to mostly cloudy skies for tonight with a chance for showers mainly in far western-far northern areas.  Low temperatures will be in the 50s with 30s and 40s near Lake Superior.  Winds will be out of the south or southeast at 5 to 15 mph.

Monday through Wednesday (April 18-20)

Strong high pressure will be centered over Ontario Province while low pressure meanders across the northern-central Plains -- There could be some showers that affect parts of the Northland on Monday, Tuesday and Wednesday but with a high sitting to our north it remains to be seen just how far north the moisture/rain will get early in the week.

(April 21-26)

A few showers are possible on Thursday-Friday (21st-22nd)  A stronger storm system could develop somewhere over the Rockies, northern or central Plains during the 23rd-26th time frame -- This storm if it comes far enough north could bring rain, gusty winds, maybe a few thunderstorms, and possibly even some snow or mixed precipitation to northeast Minnesota and northwest Wisconsin between the 23rd-26th.  Near to below normal temperatures during the long range the way it looks now.
