A Stormy DayFebruary 20th, 2014 at 6:24 am by Pamela Gardner under Colts Forecast, Weather
Current radar: Storms are moving through Indy, and the northern and eastern half of the state now. These storms are associated with a warm front.
Severe Threat: The southern half of Indiana has a slight risk for severe storms this afternoon. The time-frame is 4pm to 10pm for the severe weather. The biggest threats will be damaging wind and flooding. Tornadoes are also a possibility.
Timing: The warm front is lifting to the northeast, giving us the current storms and showers. Warmer air will get pulled into Indiana and this will help to fuel the storms later today. Storms will pop in the warm sector of the system this afternoon (ahead of the main line). Then the storms organize into a line along the cold front this evening. Forecast 8 Futurecast has storms all around central Indiana and Indianapolis at 7pm (along the cold front). By midnight the storms are out of Indiana.
Flooding: Snow melt combined with heavy rain will lead to some flooding. Rainfall potential is mainly 1″ to 2″ of rain. The snow melt equals 1″ to 2″ of water. A flood watch has been issued for much of Indiana for noon to 7pm. A flash flood watch is in effect for the southeastern corner of the state 3pm to 4am Friday. Urban and small stream flooding is the concern here. River flood warnings have been issued for the White and Wabash rivers through next week…this is due to the expected runoff.
Wind: A wind advisory is in effect this evening through Friday evening for central Indiana. Wind speeds will be between 20 and 30 mph with gusts up to 45 mph. This is aside from the storm threat. The strong wind will make tree limbs fall, could lead to power outages, and will make driving high-profile vehicles difficult.
Temperatures: Temps now are in the upper 30s and lower 40s. This afternoon we warm into the upper 50s and lower 60s. Tonight after the cold front moves through we get much colder with lows around freezing.
Extended Forecast: Cooler temperatures are in the forecast for the next several days. This weekend we have a few sprinkles with highs in the mid 40s. Sunday will by dry and cooler with highs in the upper 30s. Arctic air is expected for next week with highs in the 20s and lows nearing zero by the end of next week.
