Synopsis

The unseasonably warm air that has given the state record breaking temperatures for the past two weeks is gone and reality has finally set in. A cold front associated with cold outflow from Canada, will bring the state to its climatological norms for the week, with just one day showing a warm spike associated with an incoming storm system in the middle of the week.

Short Term

For the remainder of tonight, a tight pressure gradient will persist prior to midnight tonight, leaving breezy conditions throughout the state this evening. As the surface ridge approaches, high pressure will settle in and fully dominae early Tuesday afternoon, killing the winds and leaving only the sun to warm the state into the lower 50s. Behind this ridge, and incoming system with weak frontogenesis on the southern part will approach the state overnight Tuesday, bringing with it high clouds and faster winds ahead of its core as the afternoon and evening progress.

Long Term

The aforementioned storm system will cross over the state Wednesday afternoon. There is a cold front within the surface trough, but within the presence of little PVA and no ither surface perturbations to help it organize, the front is weak and only shows a broken line of showers moving west to east and falling apart over the mountains. This cluster will move through Wednesday afternoon, and will develop after passing the state. The low's development will be enhanced by PVA aloft that was lagging the low well behind during Wednesday afternoon, but a 500mb shortwave trough will catch up to this system overnight Wednesday into Thursday, allowing for storm development along the front (at this time toward our south) but also will give us low clouds and enhanced cold advection during the overnight hours. The shortwave will stick around throughout the afternoon, keeping the clouds and advection above and within the state, but a high will be moving on through Friday, calming the winds, nd working together with the ridge aloft to provide more sun to help us get back to the warm spring ythe state was experiencing before.
