This week will be marked by a prolonged period of unsettled weather with a chance of rain basically at any time during the week, giving May a rather dour start. However, the rain is very much needed as we are entering into the growing season with a deficit in overall rainfall. Due to the nearly continuous stretch of cloudy weather, temperatures are expected to be slightly below normal for this time of year.
Rest of today – cloudy and cool with high temperatures in the upper-50s and a chance for a scattered shower or thunderstorm through out the day.
Tuesday – overnight, a more substantial batch of rain will arrive with a wave of low pressure riding up the east coast along a nearly stationary frontal boundary. Unsettled weather continues during the day Tuesday, but chances for rain drop substantially in the afternoon. High temperatures will be a couple degrees warmer, in the low-60s.
Wednesday – we’re going to be sandwiched between the departing frontal boundary from Tuesday and another low pressure system over the Great Lakes. This will result in yet more clouds and a chance of showers during the day.
Thursday – that low pressure over the Great Lakes transfers its energy to a low pressure that will form off the coast of the Delmarva going into Thursday. Then this coastal low will just kind of spin around aimlessly in our vicinity since it will be cutoff from steering currents. This means it will be the main driver of rain activity towards the end of the week. At any point, an impulse of energy rotating around this low could spin up a band of showers. Temperatures Thursday remain in the low-60s.
Friday – basically a clone of Thursday due to the aforementioned nearly stationary coastal low.
