Breezy Early Spring Day

It should be an interesting day and definitely a Spring pattern for the area as a northern stream system will drop down across the Great Lakes and bring some light rain but more importantly some breezy conditions. With the pressure change from low pressure to our west and high pressure to our east we'll see a strong pressure gradient set up across the area and that will cause winds gusting up to 45 mph through this afternoon. You can see the isobars and they are very close together indicating that strong pressure gradient today.

By tonight this pressure gradient begins to relax a little and you can see on the map the isobars are not tightly packed across the area. High pressure from the west quickly moves in and settles things down for several hours, at least until late tomorrow afternoon and evening.
Although tomorrow looks quiet you can see another northern stream front and several systems coming from the Gulf of Alaska which are moving very quickly across the U.S. That puts us in the flow of several quick moving waves of low pressure through the end of the week.
Here is Thursday morning which promotes a strong area of low pressure which is rooted in Texas and begins a northeast track towards our area later in the day Thursday.
By Friday this weather system brings warm temperatures, breezy conditions and rain on Friday afternoon before some cooler air moves across the region by Saturday.
By Saturday morning you can see some colder air wrapped around the low pressure as it moves toward the northeastern U.S.

Greg,
I flew the Travers City, Grand Rapids, Cleavland, run tonight, and noticed that for the first time since last fall the clouds looked more like summer cumulus, than winter flat stratus clouds. I hit some moderate rain coming into Auburn around 9:30pm and had some icing at 8,000 north of Grand Rapids, but it looked more summer than winter like tonight. Maby there is hope for spring yet.
