- Quiet Weather Week Ahead
No big storms in the offing for this week with a clipper low
pushing a cold front through today bringing scattered showers. QPF
has trended downward since yesterday as model soundings show
limited moisture with a dry wedge between 5 and 8 kft AGL. There
is a chance of some weak convection across the extreme southeast
forecast area by late afternoon and evening, but most of the
global models and CAMs keep convective development off to the
south over Ohio. Seasonably cold high pressure builds in for early
in the week.
The next chance for precip is on Wednesday into Thursday as
another clipper rides the polar jet across the Great Lakes with
the steadier rain/snow ending by Friday. Cold air and some lake
effect snow showers persist into the weekend.
