Weather Underground midday recap for Monday, September 16, 2013.
A cold front approached the Southeast on Monday, which caused thunderstorms to occur in the central Midwest. Meanwhile, the same cold front, which extended into the Northeast, brought showers and thunderstorms to the Northeast coast. Spotty thunderstorms caused by Tropical Storm Ingrid affected parts of southern Texas, while similar conditions occurred in southern Florida due to an easterly flow off of the Atlantic.
The Northeast experienced thunderstorms from the Virginia coast to Maine as a cold front moved towards the Atlantic. Stronger thunderstorms along the same cold front moved through the central Midwest, which affected Kansas, Oklahoma, Arkansas, and Missouri. The northern Plains experienced temperatures 10 to 20 degrees above average as a result of a high pressure system.
A moist, easterly flow moved over southern Florida earlier today, causing thunderstorms to occur in the bottom half of the state. Across the Gulf of Mexico, Tropical Storm Ingrid made landfall over eastern Mexico, which caused spotty thunderstorms to pop up over southern Texas.
The Great Basin and central Rockies got a bit of relief earlier today as conditions stayed relatively dry throughout the region. Meanwhile towards the North, a cold front moved its way out of the Pacific Northwest, pushing showers and thunderstorms into Idaho and Montana. Behind the cold front, rain continued to persist along the Pacific Northwest coast. Towards the Southwest, warm, dry conditions occurred as a result of a dominant high pressure system.
Temperatures in the Lower 48 states Monday have ranged from a morning low of 26 degrees at Bigfork, Minn. to a midday high of 107 degrees at Palm Springs, Calif.
