high pressure over the eastern great lakes provides a tranquil labor
day. high clouds are spilling in from convection elsewhere in the
midwest, however. this activity is on the decline, so, generally
more sun than clouds today. our pesky upper-level ridge, now
centered over western mn, will exert a hint of influence overhead
today as temperatures creep up a touch warmer than sunday; highs
generally in the low-80s. the ridge tracks east tuesday and
wednesday but flattens through time as low pressure deepens over
manitoba. a trailing cold front moves through wednesday bringing a
40-60% chance of showers and thunderstorms. forecast soundings ahead
of the front wednesday afternoon show marginal support for isoalted
severe thunderstorms. lapse rates are poor, while instability and
shear are both acceptable for early autumn. stray showers may linger
into thursday morning due to the latitudinal orientation of the
occluding front atop southeast us high pressure.
while wednesday looks to be the warmest day of the week, cloud cover
permitting (upper-80s), high pressure over the upper midwest
thursday ushers in upper-70s once again. in the progressive upper-
air pattern the follows, additional chances for rain and storms
arrive next weekend.
