Winter to Spring Weather Outlook

Last Updated

While the calendar shows Spring to be starting towards the end of the week, the GFS model is suggesting that Winter will hang on a bit longer.

Following a warm start on Monday, several cold fronts will move through Tuesday into Wednesday and the upper air flow will become the somewhat amplified reminiscent of the pattern that gave us our cold weather through much of February.

While it will not be anywhere as cold, temperatures look to be below average (with some warmer breaks) through the end of March.  No major storms are predicted right now,  but getting some additional snow isn’t out of the question.  Stay tuned.

Low pressure approaching from the Mississippi Valley will bring rain to our area on Saturday.  Rain will start before midnight and imagewill be heavy before daybreak and during the morning on Saturday.  Rain tapers to showers after 2 PM and ends about 5 PM.  QPF values about 0.75 inches. High temperature about 53.

The low pressure system responsible for the rain Saturday will be slow to exit the NE and on Sunday, we’ll be influenced by a cyclonic flow around that low.   Windy conditions will make the temps in the upper 40s seem colder.   A mix of  considerable instability clouds and sunshine.  A typical March day.

Update 9:30 pm – latest models have close to an inch of rain, lasting into the early evening Saturday.
