WHAT HAS CHANGED
- Updated aviation discussion.
KEY MESSAGES
1) Generally dry weather through next Sunday. Drought conditions will worsen.
DISCUSSION
KEY MESSAGE 1...Generally dry weather through next Sunday.
Drought conditions will worsen.
KEY MESSAGE 1 DESCRIPTION...
Dry weather looks to persist through the end of next weekend.
Over the past 24 hours, models have remained very unimpressive with rain totals for the Thursday night/Friday cold front, and backed off on any rain chances for Saturday night/Sunday.
This (Monday) afternoon, a cold front is moving from north to south through the area, and will move offshore this evening.
There is very little if any precipitation with the front.
Earlier, a few spots got just enough rain to barely wet the pavement, and that is about all we are looking for. Temperatures will fall behind the front tonight, and we are looking at cool temperatures through Wednesday before we warm up Thursday ahead of the next cold front.
The next cold front, expected to move through Thursday night into Friday morning, will be much like its predecessors: generally dry, with any localized rain amounts being less than 0.10 inch.
Quiet, dry weather with temperatures fairly close to average are in store for the weekend. As said before, any rain chances should hold off until Sunday night at the earliest. Models are in pretty good agreement on dry weather through Sunday, but disagree significantly after Sunday on when/if any rain comes.
