much more than enough... (pm.10.may.16)>

Tuesday's stats:

Low temp: 59.2F (15.1C)
High temp: 77.7F (25.4C)
Rainfall: 1.35" (3.4cm) -- updated at 8pm

Currently there's light rain in progress, with some random thunder as well.  We've had rainfall in varying degrees of intensity this afternoon, and even a few periods of heavy rain between about 2:45 and 4:00pm, and again just during the past half hour or so (6:00 to 6:30pm).  There have also been some impressive episodes of hail during the spells of heavier rain.  Hazy sunshine this morning did give us a few hours of warm and humid conditions, but that was all over by about 2:00pm.

It's only the 10th of May, and I've already measured much more than DOUBLE the normal amount of rain for the entire month.  The vast majority of that came on the evening of the 5th (last Thursday), and this afternoon/evening.  For several days we've been talking about an extremely moist air mass for this time of year which has been creeping northeastward from the Arabian Sea and pushing up against the Himalayan ranges of north India.  Simultaneously, the flow in the upper-levels of the atmosphere has been coming in from the northwest, and is delivering some little disturbances/circulations which are riding over the top of this very moist air mass in the middle and lower levels.  With the steep mountain slopes acting as a trigger, we've seen the outbreak of widespread clusters of thunderstorms from western Jammu & Kashmir into central Himachal Pradesh today.

Unfortunately, the general pattern is going to remain the same throughout the week, which means we'll have to remain braced for shower and thunderstorm development each and every day, with some very heavy downpours (and hail) quite likely on occasion.  It looks like most of the action should occur during the afternoon/evening hours, so we should still come up with some sunshine here and there, and quiet interludes, in the midst of it all.  Humidity will stay unseasonably high, with temperatures running on the low side of normal for what is fast becoming the middle of May...
