This is the week when the District’s average high temperature crests 70, but I don’t see many 70+ days in the forecast. Today, in fact, we’re mostly in the 50s.  We moderate midweek and may pass 70 Wednesday, but a showery late Wednesday into Thursday period drops us back into the 60s. And with clouds and perhaps showers around next weekend, making it back into 70-degree territory might be tough.

Today (Monday): Some of our outer north and west suburbs may awaken to a bit of frost and chilled temps in the low-to-mid 30s. Then, flow directly off the Atlantic ocean doesn’t bode well for a big recovery.  Most of us see the mercury max out in the mid-to-upper 50s even with considerable sunshine at times – though tending cloudier in the afternoon/evening.  The easterly winds are around 5-10 mph. Confidence: Medium-High

Tonight: Skies are partly to mostly cloudy overnight due to the marine influence.  The clouds hold in a bit of the daytime heat so we’re not anticipating another night of frost possibilities.  Lows are mainly in the upper 30s to low-to-mid 40s downtown. Confidence: Medium-High

Tomorrow (Tuesday): Clouds in the morning should give way to partly to mostly sunny skies for the balance of the afternoon. We gain a few degrees relative to Monday, with highs near 60. Winds are from the east and southeast around 5-10 mph. Confidence: Medium-High

Tomorrow night: Partly cloudy and not as cool as the flow becomes more out of the southeast.  Lows range from the low 40s in the cooler suburbs to the upper 40s downtown. Confidence: Medium-High

A LOOK AHEAD

Wednesday may be the week’s warmest day as a warm push of air ahead of an approaching cold front probably pushes us over the 70-degree hump. Variably cloudy skies early become mostly cloudy by the afternoon and evening, with a 30 percent chance of showers and thundershowers due to an approaching cold front.  Some showers may linger overnight, with lows 42-47 (suburbs-city). Confidence: Medium

The forecast for Thursday is a bit tricky as the front slows down before exiting and weak low pressure along it may throw back some showers.  Showers or not, it’s cloudy and cooler with highs 60-65. Clearing out Thursday night, with lows in the 40s. Confidence: Low-Medium

High pressure briefly builds back into the region Friday, making for a pretty nice day, with highs in the mid-to-upper 60s.   Partly cloudy Friday night with lows in the 40s. Confidence: Medium

To be completely honest, the weekend forecast is really a tough call right now and it all depends on the timing and track of an area of low pressure approaching from the southwest.  It could arrive during Saturday or hold off until Sunday, perhaps even sliding by to the south and just grazing us.  The balance of Saturday is probably dry, but there’s a chance of showers starting in the afternoon and continuing into Sunday.  Highs are mostly in the 60s both weekend days (but could conceivably pop over 70 if the low pressure system eludes us and we end up with sunnier weather either day).  Lows are mostly in the 40s. Confidence: Low
