Mother Nature will be having some mood swings this week as a pair of low pressure systems impact the Twin Tiers. A cold front will pass through the region tonight after most of the area picks up 0.25"-0.50" of rainfall this afternoon. This will knock temperatures down to near seasonable levels in the mid 40s for Monday and Tuesday after we flirt with the 50 degree mark today. By Wednesday, strong southerly winds with a second storm system will allow for temperatures to reach the mid 50s, but a cold front will knock our temperatures back into the upper 30s for Thursday. Temperatures from there will gradually increase heading into next weekend.
