Areas affected...parts of central and northern Wisconsin into
western Upper Michigan
Concerning...Severe potential...Watch possible=20
Valid 182003Z - 182200Z
Probability of Watch Issuance...40 percent
SUMMARY...Storms will increase in coverage over the next few hours,
with areas of strong to locally damaging gusts and marginal hail.
DISCUSSION...Strong heating across the area has resulted in up to
1000 J/kg MLCAPE as temperatures rise through the 80s F. A prominent
cold front/wind shift is moving across western WI and into the
western MI U.P. with signs of deepening convection within a
pre-frontal warm conveyor.=20
Winds veering with height which may tend to favor cellular storm
mode, with a broken line of storms possible along the front. This
may favor hail initially. With time, outflows may consolidate, with
perhaps linear segments along the front aiding wind potential.
Midlevel wind speeds averaging near 40 kt along with the steep
boundary layer lapse rates may tend to favor strong outflow
production this afternoon into the early evening.
