Saturday was not the best weekend day, but at least it was dry! There was sunshine in the morning giving way to clouds by lunchtime as the middle levels of the atmosphere became more moist(but the surface was still very dry) thanks to an approaching cold front from the west; after a low of 61 at Philadelphia International Airport we reached a high of 80 this afternoon with a gusty westerly wind between 10-15mph.
Overnight will be mostly cloudy with lows in the middle 60s(lower 60s in the suburbs); Sunday itself will be cloudy with showers in the morning as the front pushes southward; by the afternoon we may actually see some sunshine with highs in the middle 80s and a northerly wind. After a clear night Sunday night with lows in the middle 60s we'll be in the lower 80s on Monday with sunshine, fair weather cumulus in the afternoon, and a northerly wind.
Come Tuesday that frontal boundary to our south will try and push northward as a warm front, but it won't make it north of the Mason-Dixon Line; there will be an area of low pressure riding along it and right now weather models have the rain staying to the south as well(a potential flooding rain event again for Baltimore is possible). Highs will be in the lower 80s, but come Wednesday there will be a short wave to the north swinging on through providing showers and thunderstorms with highs in the upper 70s.
On Thursday and into Friday it stays unsettled with a northeasterly wind and as that frontal boundary is nearby we'll have a continued lingering shower chance with highs staying in the upper 70s with overnight lows in the upper 60s. That's it for now, but remember that you can check out the 7-day forecast(as well as obtain radar and satellite maps) any time at www.scottderekwx.com/forecast.html.
