Warm Before the Cold

rb dd3e140b696188fd 10ec6ac6e92faf0b Warm Before the Cold
The transition between spring and winter has been very foggy as of the past few weeks, with a blur of motion that would hint more towards winter-time events than spring related. However, spring is a very fickle time of the year which can yield both winter and summer-like conditions. Here we are about to move into the month of April, and we are still dealing with cold spells that seem to occur rather frequently. I wish I had better news, but it does look like another push of cold air is on the way, starting the Night of April 1st.
Warmer air will build in during the weekend, putting our temperatures near the mid 50’s for Friday, Saturday and Sunday. there may also be a spot of two that could hit the 60 degree mark on Monday afternoon (if the sun does come out)! This is hope for people looking for spring, however, is nothing but a teaser. A cold front will come through Monday night that will signal the end of the 60 degree possibility at least for a few more days.

As seen above, the maximum High temperatures for the area for Monday April 1st show a slightly warmer than experienced set of temperatures than we have seen this year. This is in thanks to a southerly flow ahead of the cold front which will push warmer air into the area by Monday AM, and last until the cold front comes through Monday PM.

Now, here is a graphic showing the high temperatures, only 1 day later (4-2-2013), As you can see there is almost a 20 degree difference between max temperatures on the 1st, and 2nd. This is a big contrast in temperatures, and will likely change any precipitation we may see Monday night into some snow. At this point, it does not look like this system will have enough moisture over Connecticut to work with to make any accumulations happen. however, it will be annoying to those waiting on spring temperatures and conditions.

What is causing these colder spells of air over us? Well, there is a suppressed jet stream which has remained this way since February, allowing colder air to funnel down from Canada and leave us consistently colder than normal. This pattern has only changed slightly over the past 8 weeks, allowing a small ridge to build south of the east coast in the past week or so, allowing this small, albeit needed, wedge of warmer air to work its way towards us ahead of the next storm system. Behind the system, cold air will drag downwards from Canada once again, while the jet stream will remain suppressed once again. Thankfully the suppressed jet stream has moved some fairly large snowstorms to our south and out to sea over the past few weeks, so we will see what occurs with this latest push of cold air, and see if the upper level steering currents still support and offshore storm track. If it does occur that we have a slightly more northward track on the storm systems coming out of the plains, we may need to look very closely at the storm set-ups over the next week, as snow storms would still be possible with a colder pattern.
