Heavy rain producing flash flooding and a low threat for severe weather are the main highlights across the country through the weekend.
First, two tropical systems affect Hawaii through the weekend bringing heavy rains and breezy winds to the state. Erick will continue to weaken and pass to the south today through early Saturday with the highest impacts coming to the Big Island where flash flood watches are in effect as 4 to 8 inches of rain could fall with locally higher amounts possible. Winds across the entire state could get into the 20-40mph with gusts 45-50mph. The second system Flossie will pass north of Hawaii on Sunday and will also continue to weaken with lesser impacts on the state though more showers and breezy winds are expected.
In the lower 48 storms with heavy rain potential will mainly be around the periphery of a high-pressure system that will be in the Midwest. The best chances for storms will occur in the central Plains today, southern Plains over the weekend, and eastern UT and AZ, western CO, NM, southeast and Mid Atlantic states through the weekend. A lot of these areas could pick up 1-2 inches of rain the next 3 days with the highest totals will come in southeast NE, and eastern KS and OK today and Saturday where flash flood watches are in effect and 3-6 inches could accumulate. Severe weather chances do look low though still can't be ruled out.
