Long Range Forecasting: 1/15/17-1/22/17

It is time to look ahead at the long range forecast, as told by the GFS model.

The 300 mb GFS charts show that we never really escape troughs this week.  We don’t seem to ever be in a ridge, only a brief zonal-flow period between troughs.  I posted the 300 mb chart for Tuesday, though almost every day this week is near one trough or another.

The 500 mb GFS charts show that the strongest Positive Vorticity Advection (PVA) will occur Friday night and Saturday morning, ahead of yet another trough.

The 700 mb GFS charts show some rapidly-rising air ahead of the trough and PVA Saturday morning.  Could this be another winter storm?

The 850 mb GFS charts show no strong thermal advection over this time period, though there may be a slight cooling by Sunday morning.  It may not be enough for winter weather in the Albuquerque area, but I will be keeping my eye on this.

The Precipitation charts show that we are likely in store for another rainy weekend.  Depending on how the temperature changes, there may be some winter weather mixed in, but precipitation is likely over much of the state starting Friday.

Thank you for reading my post.
