COMPARISON OF PAST OCTOBERS.

The table shows the mean temperature, the noon temperature, and the number of days be low 320 for the past ten Octobers in south-eastern Nebraska; they are found by averaging the numbers reported at the different stations. It also shows the highest temperature and the lowest recorded anywhere in the state by standard, self-registering thermometers:

The following table shows the precipitation or depth in inches of rain and melted snow or hail, the number of days on which it fell, and the number of cloudy and of clear days. Days are counted cloudy when the sky is four-fifths overcast; clear when less than one-third. The last column shows the depth of snowfall during the month:

The daily temperature and weather predictions of the chief signal officer have been distributed by this service to the following stations, where flags have been displayed for the benefit of the public: The following are the number of failures (F), and of correct predictions (C), both as to temperature and weather:

NOVEMBER.

The month of November has been one of prevailingly pleasant weather, but with a few days of extreme temperatures both high and low. The precipitation has been normal, occurring almost wholly as snow in one or two slight falls.

PRECIPITATION.

The snowfall over the state has shown little unevenness in distribution. Only a few stations report over an inch of precipitation, this area lying along the lower Platte, and stretching up the Missouri. The greater part of the state was visited by but one slight fall of snow, from the 23d to the 25th, although an earlier and heavier fall occurred in the eastern portion on the 8th and 9th.

TEMPERATURE.

The most notable feature of the month was the unusually early occurrence of a severe cold wave, which was observed in the regions north of Montana on the 25th, and extended southward and eastward over all states and territories east of the Rocky mountains by the 2: th, causing the temperature to fall below freezing in the central portion of the Gulf and south At lantic states. The changes in temperature attending this cold wave ranged from 40° to 50° within twenty-four hours in the central valleys on the 27th and 28th. At Hay Springs the temperature fell from a maximum of 26° on the 25th to a minimum of 26 below zero on the 27th; and at Valentine from 29.2 to -31.5, a range of over sixty degrees. The mean temperature of the month has been 36.7, which is only a tifle above the normal; the highest temperature was 87°, which exceeds by over twelve degrees any previous November maximum for ten years; the maximum 31 5 below zero was lower by about twenty-five degrees than during the past ten Novembers; only twice indeed has November given temperatures below zero.

This cold wave was attended by severe winds from the north reaching a velocity of over thirty-seven miles an hour on the 27th at Crete.

This early and unexpected biizzard found many ill prepared for it, and stock suffered considerably in consequence.

FLAG SERVICE.

Except in the extreme western portion of the state the daily weather predictions have been very generally verified; the percentage of correct predictions for the state being about 92 for temperature and 91 for weather. For the far west the nearness to the region in which weather changes originate or are first discovered makes the matter of prediction more uncertain.

NOTE TO OBSERVERS:-Members of the service not now receiving the Monthly Weather Review of the chief signal officer, and desiring it, will please send in their names to the Cr te office. The sample blank accompanying this, is sent to observers with the request that they will fill out as early in the month as possible, such data as they are able and mail to the Crete office, for forwarding to the chief signal officer. If any cannot conveniently do this they will please report the fact; otherwise, a supply of these blanks will be sent. These are not intended to do away with the fuller report to the state service.
