Mesoscale Discussion 0538
NWS Storm Prediction Center Norman OK
1059 AM CDT Sun May 05 2019
Areas affected...portions of northern and central Florida
Concerning...Severe potential...Watch unlikely
Valid 051559Z - 051800Z
Probability of Watch Issuance...20 percent
SUMMARY...Limited risk for damaging wind gusts locally will continue
into this afternoon across parts of Florida. Given the limited
risk, a watch is not expected.
DISCUSSION...Latest radar loop shows a band of strong storms moving
across northern Florida, with some embedded complex structures/areas
of circulation. The background environment across the northern half
of the Peninsula is characterized by a moist/unstable airmass, per
surface observations in conjunction with morning RAOBs, along with
moderate west-southwesterly flow aloft. The CAPE/shear combination
will continue to support a few stronger cells, with locally
gusty/damaging winds possible with the strongest updrafts. Along
with the ongoing band of storms crossing northern Florida, a
second/weaker bowing band of cells off the west-central Florida
coast could increase a bit as it encounters the diurnally
destabilizing inland boundary layer.
At this time, the expected isolated and low-end nature of the risk
suggests that a watch will not be required.
