Mini-warm up, then another rain-producing storm

Sunday’s highest temperature occurred shortly after midnight, and then readings fell into the upper 30s during the morning marathon run, which saw winds gusting over 25 m.p.h. and wind chills in the upper 20s. After another chilly, windy day today, a warming trend will see readings in the 50s midweek. However, the “warmer” readings (still below normal) will signal the approach of another low pressure system and significant rainfall Wednesday and Thursday. Temperatures the next seven days should average about 10 degrees below normal.
October’s precipitation total has reached 6.20 inches at Midway Airport—the 4th greatest October total at that location. Midway’s 3rd greatest total of 8.21 inches back in 1941 may seem a reach, but it is not impossible.
In the eastern Pacific, Tropical Storm Paul may reach hurricane strength today, but is expected to weaken slightly as it approaches the southern tip of Baja California on Tuesday.
