The NWS long range forecast discussion for our area next week


.LONG TERM /Tuesday Night through Saturday/...

Issued at 142 PM EST Sat Nov 11 2017

Quasi-zonal flow ends going into this period as several mid/high
level shortwave troughs will move over the area and bring periods
of rain. First wave will move from Alberta into the Great Lakes
Tuesday and Wednesday bring the first round of rain, then the next
one will move from the Pacific Northwest into the Plains starting
precipitation possibly as early as Thursday night, more likely on
Friday into early Saturday. There is low confidence in the
precipitation starting as early as Thursday like the Euro, but
maybe wait until Friday afternoon, which is what the GFS is
leaning towards. Both models bring a southerly advection of
moisture northward into the area, so there may be some moderate
rainfall with each of these systems. At this point in time, it
looks like the Friday system, but will keep a low confidence right
now on the timing/intensity of the second storm system.

Temperatures are forecast to be into the lower half of the 50s
Tuesday through Thursday before falling into the 40s again
Saturday. Low temperatures will generally be in the mid or upper
30s with the exception of Friday morning when lows are forecast in
the low/mid 40s.
