WHAT HAS CHANGED
Aviation Discussion Update.
Although scattered showers and storms are expected to occur ahead of and along a front later today into tonight, the confidence in severe storm development is low.
KEY MESSAGES
- 1) Breezy conditions develop ahead of a front today, with potential for showers and storms increasing later this afternoon into tonight. A few strong storms could be possible.
- 2) Another front brings a chance of rain and storms late Sunday into Monday, then additional precipitation chances accompany a couple of mid to late week systems.
DISCUSSION
KEY MESSAGE 1...
Strong winds aloft begin mixing down to the surface later this morning, with breezy conditions expected to persist through the majority of the day as a cold front approaches from the northwest.
Scattered showers and thunderstorms begin to develop in advance of the front this afternoon. Although shear may be strong, forecast soundings suggest mediocre instability which slightly lessens confidence in severe storm development. That being said, SPC has maintained a marginal severe weather risk across the area as daytime heating could prompt a few stronger storms to develop and produce locally damaging wind, hail, or maybe even a tornado.
The severe weather risk should gradually diminish after sundown, then precipitation comes to an end once the front crosses the area overnight. Drier conditions are then expected to take hold for the first half of the weekend.
KEY MESSAGE 2...
Another front brings potential for scattered rain showers and storms late Sunday into Monday, with breezy conditions likely developing prior to its arrival. Sunday's above normal temperatures are expected to give way to near to below normal temperatures in the wake of the front.
A couple of passing systems could facilitate additional chances of precipitation mid to late next week; however, the timing and track of these systems is uncertain at this point.
AVIATION /08Z FRIDAY THROUGH TUESDAY/
After a VFR morning, periodic MVFR to IFR restrictions will be possible within scattered storms and heavier showers this afternoon into tonight. Precipitation comes to an end once a front crosses the area overnight, though sub-VFR conditions remain possible into Saturday morning due to low ceilings.
A brief period of LLWS could be possible before gusty winds mix down to the surface later this morning. Gusts of 15 to 25 kts are then expected to persist ahead of the front, with locally stronger gusts potentially occurring in storms.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z SATURDAY...
FORECAST CONFIDENCE: Medium.
ALTERNATE SCENARIOS: Brief LLWS may be possible this morning.
