Significant Weather Outlook: Tuesday, April 14, 2026 9 AM
Significant Weather Weekly Outlook
A broad, large subtropical upper-level ridge is bringing warm temperatures to southern New England this week. As one might surmise, temperatures this far above normal cannot be expected to be sustained for a long time in April. A series of troughs will erode the ridge late this week into early next week. This will bring temperatures back to near, if not a little below, average for this time of year.
Isolated Strong to Severe Thunderstorms Possible Late this Afternoon or Early Evening
Sufficient instability and vertical wind shear exist to create the potential for late afternoon/early evening thunderstorms that may bring isolated and highly localized strong, even possibly damaging, wind gusts to interior southern New England. The greatest risk for any strong to severe thunderstorms would be across western MA and northwest CT. Since there is no front or other strong forcing mechanism, a widespread severe weather outbreak does not appear likely.
Monitor information from your local National Weather Service office with respect to any watches or warnings that may be issued. It is not practicable for this blog to chase any individual Severe Thunderstorm Warnings.
Rest of the Week/Weekend
Wednesday will likely feature more warm temperatures and a risk of widely scattered afternoon/early evening thunderstorms.
A fairly vigorous fast-moving upper-level trough and surface cold front may trigger numerous showers and scattered thunderstorms Friday afternoon/evening. A few of those thunderstorms may be strong, but it’s too far ahead for an accurate appraisal of any severe potential.
A still higher amplitude upper trough and strong surface cold front will likely bring widespread showers and possible thunderstorms to the area Sunday/Sunday night and usher much cooler air into the region. Temperatures will drop to near or even a little below average for the start of next week.
Next Message
The next message will likely be the significant weather weekly outlook scheduled for Monday April 20 unless localized severe weather potential necessitates a blog issuance before then.
