major pattern change in progress

Posted on September 27, 2010 by Mitchell Gaines

Overall we have low pressure moving up the east coast with a nice pipeline of tropical moisture. Low clouds and light showers will be present on the backside into Tuesday. Also NW flow will be in place for the week. This means highs will be more seasonable in the 70’s with lows in the 50’s.  If you’re wondering why we’re seeing this pattern change one may look to the PNA which has been running strongly negative for a while now has becoming strongly positive and the AO will be going negative as well. This sets up for a period of normal to below normal temperatures over the next 2-3 weeks.

    Tommorow’s update will look at the 12z candian run which implies a rainy Friday and phases niciole with a great lakes trough with a finale of snow showers over the great lakes by Sunday.
