FLOOD WATCH IN EFFECT FROM THIS MORNING THROUGH SATURDAY AFTERNOON
When it rains, it pours
To put things in perspective, we may record 20 to 40 times as much rain in the next couple of days as we have had in the last five weeks. Numerous ingredients are coming together for a very heavy rain event. This National Weather Service forecast discussion lists them:
DEEP TROPICAL MOISTURE WITH PWS NEAR 2.5 INCHES (CLOSE TO 300% ABV NORMAL)...AN ANOMALOUS H85 40-KT JET TO HELP FOCUS UPSLOPE FLOW...K INDICES OVR 35...A SLOW MOVING BDRY TO FOCUS RAIN OVER A SAME AREA...STRONG UPPER DIFLUENCE AT H25...AND VERY HIGH FZL LVLS (16KFT) INDICATING PRECIP WILL BE DOMINATED BY WARM RAIN PROCESSES.That's a lot of meteorological jargon. It just means that all the way up through the atmosphere and all around us, conditions are ripe for an extended deluge.
Here's my rainfall forecast for today through Saturday night:
Rain Event Evolution
Morning rush today: Steady rain begins (chance near 100%), Temperature 68
Lunch today: Heavy rain (chance near 100%), Temperature 70
Evening rush today: Heavy rain (chance 90%), Temperature 69
Overnight: Rain (chance 80%), Temperatures 64-67
Saturday morning: Rain (chance 70%), Temperature 66
Noon Saturday: Heavy rain (chance 70%), Temperature 68
Saturday evening: Heavy rain (chance 60%), Temperature 67
Overnight Saturday: Chance of showers (chance 50%), Temperatures 55-59
Sunday: Chance of rain (chance 50%), Temperatures 64-68
Yes-- the weekend will be crummy, but it's payback for the string of beautiful dry weekends we've had.
