Severe weather risk overnight tonight and again tomorrow afternoon

A calm before the storm. Highs today will be in the low to mid 60's. Lows will be only be in the 50's overnight. Rising dewpoints and showers and t-storms becoming severe by morning. A big boost in temperatures tomorrow with near record high temperatures. Highs in the mid 70's. Old record leap year 77. Wow! This will increase our storm development. Where this exactly setup tomorrow afternoon/early evening? Is still unknown. A break Thursday. Friday more showers/t-storms. This could become severe especially late Friday. Highs looks to warm into the mid 70's. Turning colder Saturday with a chance of lingering showers/t-storms. Most  models are still indicating snow chance Sunday late into Monday. The timing been push back. After that it looks like it will quickly warm up.
