SJ-Weather_withJR_small-square_web-300x300

Today begins with blue skies and cold temperatures then by mid-day the next trough of low pressure dropping south from the NW will begin snow production for the south San Juans, this is the first of three storms we’ll see through the weekend. The system is arriving on southwest flow so the south SJ’s will be favored again.  South west terrain above TL could see up to 18″ (Wolf Creek) but will probably average 6-10″.

The storm will kick in later this evening as it moves to the NE into the central and northern mountains and by later Thursday afternoon it will be spent. The active pattern continues with another low pressure trough arriving late Thursday/early Friday morning bringing another round of snow (3-6″) into Saturday then the final storm on Sunday (3-6″). We’ll dry out for a few days when mid-week more storm energy will make it’s way from California.
