Saturday, January 3 - Sunday, January 4, 2015 - Clouded out for the Quadrantid peak
By midnight as Saturday the 3rd began, the peak of the Quadrantids was less than 24 hours away (since the IMO was predicting it for 9:00 PM EST January 3, or 2:00 UT January 4). As expected, conditions in my area made observing anything impossible. There was such a thick cloud overcast that not even the bright Waxing Gibbous Moon could be seen. By 1:00 AM light rain showers moved in, and rain and drizzle continued for the next few hours. Temperatures remained just above the freezing point, so by 4:00 AM I saw no sign of freezing rain, sleet, or snow. I also noticed that the National Weather Service had removed the Winter Weather Advisory from counties just to our north, though it remained in place for the northern third of Indiana.
By sunrise (8:06 AM) we'd climbed to 35°F, and temperatures kept climbing all day long. At the same time, bands of rain kept moving through all during the daylight hours and winds were light to moderate. At sunset (5:32 PM) we'd reached an unreal 52°F. It was a gloomy, wet, and muddy day, but at least the air felt springlike! I should also mention that the Air Pressure fell from 30.18" near the start of the day to 29.73" by 5:00 PM as the center of this low pressure system passed, then started to recover a little after dark.
After dark on the 3rd, the back edge of this big system with the cold front started to work its way into the area. The main line of rain had moved on, but smaller bands started to enter Indianapolis by midnight. Winds also started to pick up. At midnight we were back down to 44°F with a wind chill a few degrees colder.
The best time for me to observe the short, sharp-peaking Quadrantid Meteor Shower would have been from midnight to dawn on Sunday the 4th. The display would have been winding down by that time, but I'm sure I still could have seen several. But the weather just didn't cooperate at all. For hours after midnight we had periods of light rain and drizzle along with mist and fog, then maybe some broken clouds around 4:00 AM - 5:00 AM, but definitely overcast skies from dawn through sunrise (at 8:06 AM again). Winds became strong and gusty. By sunrise we'd dropped to 34°F but wind chills were in the low 20's°F range. The Pressure fell back to 29.73" between 3:00 AM - 5:00 AM before starting to rise again.
After daybreak on Sunday, things didn't improve much. The sky stayed gloomy and overcast and we had some brief periods of light drizzle and light rain. Winds remained strong and gusty. By 10:00 AM we'd dropped to the freezing point, and by Noon we were down to 31°F with a wind chill of 20°F. By 1:00 PM a mix of rain, sleet, and snow pellets starting falling; the gusty winds made the ice bits "ping" against the windows. As the afternoon went on this changed to bigger flakes of snow whipped by the wind, and it fell hard enough to whiten the grass. This was the first real coating of snow I'd seen in over 2 weeks, and it was also the first measurable snow of 2015.
Sunset on Sunday was at 5:33 PM. By dusk it was still windy with light snow falling. Roads were starting to get slick with ice patches here and there. The snow tapered off later in the evening, but it remained overcast, windy, and cold through midnight. By midnight it was 12°F with the wind out of the west at 18 mph giving us a wind chill of -5°F. (Wind gusts at midnight were still as high as 29 mph!)
Full Moon occurred at 11:53 PM EST on Sunday the 4th (4:53 UT January 5). There may have been a few fast-moving "holes" in the overcast by midnight, but it was too cloudy to even get a decent naked-eye look at the Moon.
And that was how this year's Quadrantid Meteor Shower went for me this year. As I've written, it would have been a difficult shower to observe anyway because of bright moonlight interference, but in the end it didn't matter since the big weather system interfered anyway! The next major annual meteor shower was over three months away; so this part of my amateur astronomy hobby was over for a while!
