Tuesday’s Severe Weather Outlook

1:45PM

A storm system will continue to works its way across the Plains, while another system continues to slowly push out of the Northeast. I have issued a slight risk for severe storms on Tuesday. Storms will be ongoing in the Morning across portions of Texas, Oklahoma, Arkansas, Louisiana, Minnesota, Nebraska, North Dakota, Kansas, and Missouri. Some of these storms will produce heavy rain. In the Plains, in the Afternoon, SB CAPE will get up around 3500, ML CAPE around 3000, LI’s of -7, and Effective Bulk Shear of 40-50KT. This combined with a system moving through the area will help cause severe storms to develop. The storms will push east and southeast through the Evening, and may form into one or two MCS’s as the low level jet kicks in. In the Gulf coast States, in the Afternoon, SB CAPE will get up around 2500, ML cAPE around 1000, and Effective Bulk Shear of 25-40KT. Combined with a system moving through, this will cause storms to develop, some will be severe as they move east from Louisiana toward Alabama by Night. Threats from any severe storms will be damaging winds, hail, and an isolated tornado. Below is my severe weather outlook for Tuesday.
