By Friday into Saturday we will be watching high pressure build from the Atlantic.
After a hot day Monday, temperatures will be below normal for the remainder of the week. Scattered showers should increase again during the afternoon, with a line of heavier showers and storms likely approaching from the west toward evening, as a cold front approaches from that direction. The biggest change in the forecast today will be a cold front helping to spark bigger and possibly severe thunderstorms across the eastern plains. Highs will top out in the mid-80s, though possibly becoming a bit cooler along Lake Michigan. There are many at the moment, and more are possible as the rain continues for another day.
A coastal storm that's bringing scattered thundershowers and gusty winds to Long Island overnight is kicking off an unsettled stretch that will see more chances for wet weather. Rainfall totals through Wednesday night range anywhere from 5 to 10 inches, but many spots could have locally higher amounts than that. High temperatures today and tomorrow will be around 80°.
More heavy showers and thunderstorms are possible through Wednesday. Temperatures are near 80 degrees depending on shower timing and coverage
Just like the last few days, it won't rain the entire day and night and in fact much of the time may remain dry. While flooding is possible through Canon City, rain looks heavier north and south of the city.
The trend of afternoon showers and thunderstorms will continue Tuesday through Friday, with storms capable of producing damaging wind, large hail and frequent lightning.
