26 Ninth Annual Report of the 



Our weather conditions were influenced this niontli bj six areas 

 of liigli, and seven areas of low pressure ; the latter numl)er being 

 less than the usual storm frequency for January. The depressions 

 generallj' passed in the vicinity of the great lakes, and thence 

 down the St. Lawrence valley ; storms of this class being nearest 

 New York on the 5th, 10th, 18th, 2 1st and 23d. A deep depres- 

 sion developed in the St. Lawrence valley on the 26th, and a severe 

 cyclone passed northward beyond the coast line on the 28tli. The 

 first low spread over eastern Canada on the ith, giving warm south- 

 erly winds and general rains, turning to sleet and snow in the rear 

 of the storm. The storm of the ISth also brought a warm wave, 

 general light rains and snow, with the maximum wind velocity of 

 January, and the gales continued with but little intermission until 

 the end of the month. The three depressions which passed near 

 New York during this period were strongly developed, bringing 

 heavy snows in various portions of the State. 



The high pressure systems were principally felt in this vicinity 

 about the 1st, 8th, 13th, 20th, 25th and 31st. AU excepting the 

 fourth were strongly developed, and gave a decided fall of temper- 

 ature in passing over the eastern States. The high ^vinds and cold 

 weather of the last decade occurred coincidently with an extraordi- 

 nary increase of pressure in the northwest, the minimum temper- 

 atures for the month occurring on the 25th, when the anticyclonic 

 system spread eastward to ihe coast. The highs generally followed 

 a more northerly course than usual, passing centrally in this 

 vicinity. 



Reports from 38 observers show that on the 15th the depth of 

 snow on the ground averaged about 2 inches or less, although in 

 Bortions of the Adirondack hio-hlands a foot or more was measured. 

 The depth on the 31st averaged about 10 inches, the measurements
