Tomorrow looks tranquil, but Saturday is interesting!
We have a 12-hour spring ahead, caused by this big bowling ball storm with flooding rain coming into L.A., San Diego & Yuma to Phoenix. This is buckling the jet pretty wildly & will bring this big storm & burst of warmth Saturday.
1. The good news is that the heaviest, most widespread rainfall is morning to midday. It will be much more scattered for parade time & the temperatures will be mild. The sun will also appear at times, making it feel like a March, not December parade.
2. The bad news is that the winds will be strong from the southwest with gusts to 45 mph at times. Also, there will be scattered showers & t'storms pivoting through off & on afternoon, through parade time. There is also a MARGINAL RISK of severe weather with any of those scattered t'storms that pivot through.
3. So..............widespread heavy rain with a few t'storms morning to midday with howling southeast winds to 45 mph & temperatures mostly in the 40s. Up to 1.25" of rain may fall in a 5-hour period, leading to localized ponding/flash flooding.
4. The sun should come out & cumulus towers bubble up like spring in the afternoon. Winds will turn to the southwest with gusts 35-45 mph.
5. As those clouds build, some spokes of fast-moving scattered showers & t'storms will develop & pivot through during the afternoon as temperatures soar rapidly to near 62. A more organized, fast-loving line of showers & t'storms are possible in the late evening.
6. There is a MARGINAL RISK of severe weather in the mid to late afternoon to evening from any of these spokes of scattered t'storms that pass through. This means an isolated severe storm or two is possible with the main threat being wind. Some small hail is also possible.
7. So, for the line-up & actual parade, count on temperatures 58-63 with howling southwest winds, clouds with some sun (initially when the sun is still up) & with the potential of a couple passing brief showers/t'storms.
8. We should clear & dry out Saturday night, before low clouds & showery weather returns Sunday with falling temperatures from the 40s & 50s early to the 30s & 40s in the afternoon-evening. Winds will still be strong Saturday night-Sunday with gusts to 40 mph at times from the southwest, then west to northwest.
9. Total rainfall Saturday-Sunday will run 1.25-2", resulting in lowland flooding next week along the Wabash River.
