Daily Weather in Nepal

This week we'll be diving into a typical three day forecast for this time of year in Nepal's capital city, Kathmandu. I looked at Kathmandu's forecast for 11/5/14-11/7/14.  On Wednesday the 5th the forecasted high is 70 degrees with a low of 53 degrees Fahrenheit. The precipitation percentage for the 5th is 50% with a good chance for light showers. Progressing to Thursday the 6th there is a forecasted high of 72 degrees, a low of 52 degrees Fahrenheit and a chance of precipitation at 6%. Finishing up on Friday the 7th there is a forecasted high of 77 degrees, a low of 53 degrees Fahrenheit, and a precipitation percent of 4%. Over the three day period there was an average pressure of 30 inches, with no change in pressure. The average wind speed is predicted to be 4.6 mph, with a steady unchanging speed over the three day period.  Overall, it will be a pretty similar three days this week Wednesday through Friday, so worry free weather is on the way.

Above you can observe a satellite image from a little earlier than this post will be published. There are clouds in the Himalayan mountain region just north of Kathmandu.  They are relatively far but in respect to proximity to the mountains they are fairly close. They are a mix of cold clouds near the summits of the mountains, while at the bases of the mountains there are low and warm clouds. This can be observed by noticing that the cold clouds are blue while the low warm clouds are grey and white. From what I could observe on the radar portion of the satellite image there was no precipitation in the Kathmandu region at this point in time. The surface characteristics of Kathmandu itself are mostly forest and parks. It is in a circular shape placed in the middle of hills and mountains. In the middle of the circular shape of Kathmandu lies cityscape with bridges over local rivers like the Bishnumati, Bagmati, and Manohara rivers that run throughout the city.

Looking at the large-scale regional pattern of low and high pressure and fronts for Kathmandu, we can look at Asia as a whole. There is a large high pressure system Northeast of Nepal that keeps the weather mild a majority of the time. South of Nepal there is a low pressure system in the Indian Ocean. To the West of Nepal there is a cold front along with a stationary front northwest of Nepal. The warm moist air from Nepal's subtropical climate circulates into the stationary front while thunderstorms and showers can occur near the cold front. In the center of Nepal there is a High pressure system assuring mild seasons.

The closest small-scale surface analysis map to Nepal is India. Being located between India and China Nepal is effected by both large regions pressure systems.The low pressure system in the Indian Ocean reading at 100mb does have an onshore effect to Nepal with an extending isobar of 1012mb.  This low pressure system is the source of the Asian Monsoon. This usually ends up being the only substantial weather occurrence during Kathmandu's year.
