Storms in the south block moisture further north

A weak upper level disturbance will keep the cloud cover in and out today with only a slight chance of a passing shower later this afternoon.  Once that passes Canadian high pressure moves into the Midwest and while it will bring a slight cool down temperatures will still remain above average; highs will be in the upper 30s

Further south a developing low pressure system will move through the Gulf states and into the southeast by Saturday night.  This brings the threat for heavy rainfall along with the potential for severe weather - especially Saturday.  The low is in the 'developing stages' today so a few storms may fire across Texas and Louisiana this afternoon.  As the low moves east it will gain a little more support from the upper levels as a cold pocket of air aloft interacts with the warm, moist surface.  The greatest threat for severe weather exists from far southern Louisiana, Mississippi, Alabama and the Florida panhandle.  This could also bring heavy snow to parts of the Mid-Atlantic by Sunday.  Despite our southerly winds this afternoon moisture will remain confined to the south due to the developing low.
