One word for Sunday is WOW! Temperatures have soared into the low 80s with a pleasant southerly breeze…WOW! It finally is feeling a lot more like spring, if not summer, this Sunday.
High pressure has brought us beautiful sunshine and fantastic weather this week. It will begin to push east into the Canadian Maritimes as a warm front moves north across New England. This warm front stretches from an area of low pressure that is gathering strength across the Plains. That area of low pressure will bring rain to our region but not until Monday night at the earliest, lasting through Tuesday.
For now, though, things will stay dry. Sunday we will see lows in the upper 50s to near 60, which is well above average for this time of year.
Meanwhile, the storm system causing lots of severe weather in the Plains is heading our way, but the severe energy should be sucked up by the time it arrives in Maryland. We could get a few rumbles of thunder, but this is going to be mainly a rain situation for us and we could see anywhere from 0.5″ to 1″ of rain. Rain will arrive Monday evening from west to east and become widespread on Tuesday. The Tuesday evening commute will likely be very messy… but only because of heavy rain
Then there is the teeny tiny possibility of a few wet snowflakes on the backside of this system, mostly likely between 10 p.m. Tuesday and 2 a.m. Wednesday. Main threat will be north and west of the city. Cold air will work its way in on the backside of a cold front that moves through Tuesday. Temperatures will drop below freezing Tuesday night. If this happens while we still have precipitable moisture around, yes we could see a few wet snowflakes… or at least some flakes mixing in with rain. This will be brief (if it happens at all) and NO ACCUMULATION is expected. At least that’s how things are trending with the models. There is no need to freak out about this, but it is worth talking about on Monday during the shows if the models are still trending this way… being that highs Sunday were in the low 80s and Monday we will be awfully close to 80 as well. Talk about a 180 degree weather turn-around! By Wednesday, highs will only make it into the low 50s.
