Nice week ahead.. Major cool down next week?

It should be a fairly nice week ahead across southern MB with generally near normal temperatures much of the week. There will be a band of rain moving across the Red River valley Tuesday night into Wednesday morning (perhaps 5 mm or so), but the rest of the week looks dry and seasonably mild with highs in the 10-13C by Friday or Saturday.  Unfortunately long range models are showing a significant outbreak of cold weather by Sunday the 26th which will likely result in below normal temperatures for the last week of October. In fact, if the models are right, the airmass will be cold enough for the first snowflurries of the year across much of southern MB, with the potential for snowsqualls off the MB lakes.  So be prepared for a chilly Halloween (yet again!), along with the possibility of some of the white stuff around.
