Discussion
An upper-level low pressure system will move over the northeastern quadrant of the nation today and keep it unsettled around here for the next couple of days. This system will result in unstable conditions in the atmosphere with unusually chilly air aloft for the early part of May. Any kind of early day low-level heating today and tomorrow will act to destabilize the atmosphere and the result is likely to be scattered afternoon showers on both days. There can even be a thunderstorm on Saturday afternoon and with the freezing level at such an unusually low level, small hail will be possible. Another low pressure system will head northeast on Sunday and is likely to bring us thickening clouds and more rain to the area later in the day and on Sunday night. The cool and unsettled weather pattern that is unfolding will likely last for the next ten days or so across much of the northern US.
