This week (May 8-14) will be a pretty ugly week with rounds of clouds and sun and occasional showers plus cool temperatures, and it’s all because of an omega block. With an omega blocking pattern, it puts storms at a standstill, so the same storm that we have been dealing with since Friday, May 5, which brought the heavy rain to town, will still be sitting over the Northeast this entire week.
Monday, May 8: Monday will be the worst day of our seven day stretch because temperatures will be at their coldest. How about highs only reaching the mid 50s and morning low temperatures being in the 30s?! That’s going to be a reality this Monday. At least the sun will be shining with sunny to partly cloudy skies in the forecast along with the stray shower chance.
Tuesday, May 9: The omega block pattern that I mentioned will continue to take over the Northern Hemisphere, therefore the same storm from Friday will remain overhead. Now of course the storm will be dramatically weaker, but that will keep the rounds of clouds, cool temperatures, and spotty showers around. Specifically on Tuesday, you can expect sunny to partly cloudy skies with temperatures similar to Monday.
Wednesday, May 10: Then on Wednesday, the weather will be warmer but still not very springlike–maybe we have a shot at hitting 60 degrees, but our average high for this time of the year is 65 degrees. Wednesday should feature sunny to partly cloudy skies once again.
Thursday, May 11: Now on Thursday and Friday, the upper-low, which is the storm that hasn’t moved since last Friday, should break down and push off to the east, but a brand new storm will enter the picture, leading to a new enhancement to the jet stream pattern or omega block. For Thursday, expect a mix of sun and clouds with the chance for a shower or two, although recent data suggests that Thursday will remain dry.
Friday, May 12: Then on Friday to wrap up the week, there is the chance for another shower, especially in the morning. Otherwise it will be a relatively mild day under partly cloudy skies. Hopefully it will be nice for the Wilton Junior Prom in the evening.
Saturday, May 13: Saturday will feature the third chance in a row for a passing shower due to the very unsettled weather pattern, but other then that it should be a pretty nice day, featuring sunshine and a few clouds and highs in the upper 50s.
Sunday, May 14: Sunday should be slightly milder with highs around the 60 degrees mark. Morning sunshine for Mother’s Day may give way to clouds in the afternoon. Looking ahead to next week, the omega block pattern should break down, meaning that more sunshine and warmer temperatures will return, if that pattern dissipates.
