EXTENDED FORECAST (Trigger Graph)
This product extends out 7 days in advance to give you a good idea of what to expect on the horizon. It features timing, temperature and precipitation potential. Meanwhile, we take our best shot at potential snow totals (Triggers) for upcoming storms. The perfect piece of information if you need to plan ahead.
TEXT UPDATE/WEATHER BRIEFING
Busy 60 hrs. is in front of us, so let's get right to it.
First off, there is potential for a Coating to 2" of snow between Midnight & 6am Saturday. After that, spotty freezing drizzle appears likely much of Saturday.
Now, lets get to the major Winter Storm for the 2nd half of the weekend. Attached is the latest 'Timing Graph' for later Saturday PM into Sunday AM. Notice that I'm worried about a thin layer of ICE during the afternoon hours before everything changes to SNOW Saturday evening. Here is the blueprint on this weekend's system:
Timing of accumulating Snow: 6pm Saturday to 6am Sunday.
Snow/Liquid Ratio: 10:1 to 14:1
Pavement Temps: Below 32 degrees.
Snow consistency: Moderate to Heavy = Difficult to move around.
Snow potential: 3" - 6"+ (Tight snow gradient develops near the MSP metro with higher totals as you travel east & south).
Ice potential: Saturday afternoon.
Height of the Storm: 9pm Saturday to 3am Sunday.
Winds: Increasing to 25 to 40 mph by Sunday AM.
Bust Potential: Moderate
Important Note: There will be a sharp NW/SE snow gradient setting-up across the MSP metro. The lower totals are expected on the northwest side of the metro. The axis of heaviest snow is expected from Ames, IA to Rochester MN to Menomonie, WI.
Also, attached is the latest 'Trigger Graph'. Notice that our weather pattern settles down after this weekend. In fact, I'm not expecting any significant snow next week. This will give you an opportunity to get some much needed rest. However, temperatures will continue much below average for much of the period.
More to come later today.
Best of luck this weekend.
