.SHORT TERM...(Today and tonight)
Issued at 212 AM CDT Wed Jul 26 2017

Quiet through the short term. Drier air will accompany surface

wave trough over eastern North America retrogrades and deepens a bit
with building upstream ridge. Flow aloft becomes more northwest over
the Northern Plains.

The GFS and the ECMWF are in reasonable agreement at the beginning
of the period but quickly become out of phase by 12Z Mon over
eastern Canada. Both the ECMWF and the GFS were trending slower and
farther south and west.
