This is usually the best time of the year for skywave to pop up early in the afternoon. Sometimes, it lasts all day! One early morning, back in December '79, I was totally taken aback by hearing "You're in Q-Country..... 1570, CKLQ!". That reception was clear as day! Winnipeg, Manitoba to Westfield, MA is 1300 miles as the crow flies! Got a nice QSL letter from CKLQ a few weeks later. I only had about 30 seconds of getting them, but the ID was as clear as day! (They have since moved to 880.). This is the best time of the year, right now. You should start getting skywave around 2 hours before your local sunset. If you're daring enough, try a little earlier. Also, if you have snow cover in your area, don't be surprised to see some enhanced groundwave and skywave. Last year when the northeast was covered with snow and the temperatures were well below freezing, I was getting enhanced reception, especially in the higher frequencies above +1100 kHz from stations over 400 miles away! Enjoy!
