National Weather Service Denver/Boulder CO
950 AM MDT Sat Jul 19 2025

If conditions become unrepresentative...contact the National Weather
Service.

.DISCUSSION... Scattered afternoon/evening showers and
thunderstorms are possible today. A few of the storms may become
severe with gusty outflows and larger hail possible. LaSalle is
right on the gradient of where the stronger storms are anticipated
to strengthen, so there is about a 50/50 chance they remain below
the severe thresholds for your area, but gusty winds between
30-50mph and lightning will be a threat either way. Conditions are
expected to stabilize quickly after sunset, with a chance for a
few wind shifts due to outflows from storms to the east, but
generally light SE winds should take hold by 9 PM.
