Our next snow potential is showing up in the 7day forecast, next Tuesday night into Wednesday.   It's certainly not a guarantee, and lots can change between now and then.  Follow along with the descriptions and maps below.

So, first off, when looking for a snow chance a long ways out there are some things we need to see happen.  First, we obviously need to see a significant temperature drop.  Second, that temperature drop needs to happen at the same time as some sort of storm (strong or weak) is moving through, because we need precipitation. 

The first map below shows those two things.  The column of air is cold enough for snow (500-1000 thickness, the 540 1st blue line (rain/snow line) is well south of our area).  Also, you can see green over our area, indicating at least some light precipitation happening.

This next map is the total snow accumulation prediction from the GFS model.  While this likely won't happen, it does show at least some confidence that snow could occur.  Most likely, much of the snow (if it happens) will melt on contact, with temperatures at or above freeze, thus more melting, and very little or no accumulation.

The following two maps show the precipitation type from the GFS weather model for Wednesday morning through early afternoon.  Blue = Snow.

The last map is our long-range Futurecast model showing the system over our area early Wednesday. Highs Wendesday may only be in the upper 30s and low 40s, with lows in the 20s!

So, again, while there is some consistency in the models putting out snow over us for next week, the forecast is still highly subject to change.  It'll be fun to keep an eye on over the next several days.
