Today will be another warm day in the DC metro region featuring plenty of sunshine and an increasing S-SW wind. A cold front crosses the region later tonight and it’ll become noticeably cooler on Thursday with a northwesterly breeze on the back side of the front. It stays cool on Friday and the weekend begins with comfortable conditions ahead of the next cold front. That front will pass through on Saturday and usher in cooler air for Sunday and Monday with high temperatures likely confined to near 60 degrees on both days despite plenty of sunshine.

Today will be the warmest day of the week and possibly a record breaker in some spots with afternoon highs in the lower 80’s. It stays warm on Wednesday ahead of the next cold front, but will turn breezy and noticeably cooler for Thursday and Friday. The weekend starts off comfortably cool on Saturday and then becomes even cooler for Sunday as a second cold front will cross the region. In terms of rainfall, the chances are quite small for the next few days with only the chance for an isolated shower during the weekend as the next cold front arrives.

Since the middle of last week, two separate tropical systems attained tropical storm status adding to the year’s total number of named storms to 15 in the Atlantic Basin. Neither one of these most recent tropical storms, Nadine and Oscar, are a threat to the US mainland as the first one has already dissipated and the second is destined to push out over the open waters of the western Atlantic Ocean. There are signs, however, that tropical activity in the Atlantic Basin may be very well get boosted again as we push into the first half of November.

The main theme of the weather this week will be “dry, dry and more dry” with little chance of rainfall around here as has been the case all month long. High pressure remains in control as we begin the new work week and the next system of note will be a cold front that passes through on Wednesday night…without any rainfall. Temperatures will climb well up in the 70’s today and to near 80 degrees tomorrow afternoon, and then cool down later in the week following the mid-week frontal passage.

Very strong high pressure throughout all levels of the atmosphere remains parked over southern Canada and it will keep us dry and comfortable for the next several days along with plenty of sunshine. Temperatures have been running at well below-normal levels for the past few days, but will begin a climb today featuring afternoon highs well up in the 60’s, and then 70+ degrees is possible on both weekend days. The dry weather pattern continues in a month that has featured very little, if any, rainfall in the DC-to-Philly-to-NYC corridor.

October can be a dry month in the Northeast US with the usual overall cooling down of the atmosphere, but this one has been pretty ridiculous. While tropical moisture has inundated the Tennessee Valley/Appalachians and Southeast US during the past couple of weeks, nary a drop has fallen in the DC-to-Philly-to-NYC corridor and there is not much reason for hope in the next week or so. Perhaps...just perhaps...there may be some decent rainfall here around the end of the month as a strong cold frontal system heads this way from central Canada.

Strong high pressure centered nearby will stay in control of our weather during the next couple of days with a chilly air mass remaining in place. Temperatures will be stay below-normal today with afternoon highs likely in the upper 50’s and overnight lows should be near 40 degrees across many suburbs. It turns a bit milder on Friday and the weekend is looking quite comfortable with sunshine expected on both days. One final note, the comet will remain visible in the western sky during each of the next few evenings assuming favorable sky conditions and a “dark enough” environment...look to the west about 45 minutes after sunset and binoculars are recommended.

A strong cold front passed through the region on Monday and ushered in the chilliest air mass of the season so far. Temperatures for the next few days will be well below-normal for the middle of October and there can be frost in the overnight hours in some suburban locations with lows down in the 30’s. It turns a bit milder by the end of the week and the weekend is looking quite comfortable with sunshine likely on both days.
One other note, a comet should continue to be visible in the low western sky during each of the next few evenings given favorable sky conditions and “dark enough” environmental conditions….rough time period for viewing is 7:05-7:25pm...wonder what the ”Over/Under” was on seeing the northern lights and a comet within a 5-day period?

Last week, it was the northern lights and now - for another astronomical treat - a comet should be visible to the naked eye during the next week to ten days or so in the western sky after sunset. Comet Tsuchinshan-ATLAS has now exited the sun’s glare having come closest to the sun in late September. It made its closest approach to Earth this past Saturday, October 11th, passing about 44 million miles away. It is now rising a little bit higher each night in the western sky and remaining visible for a little bit longer period; however, it is also going to lose some its brightness with each passing day.
