I just checked the IMD site and there doesn't seem to be any cloud cover on Himachal and J&K. But then the short term forecast shows that it shall rain in Keylong and that too to the tune of 50 mm+. http://imd.gov.in/section/nhac/distforecast/lahaul-spiti.htm 50 mm of rain means atleast 6-8 ft of snow at higher reaches. Same is the case for Leh... http://imd.gov.in/section/nhac/distforecast/ladakh.htm I don't know, how accurate it is but, we have seen that short term forecast of IMD is preety accurate. But then there is no severe weather warning for greater Himalaya region..
