Since last three to four days, moderate rains with a couple of heavy spells have been lashing a few regions in Rajasthan. In fact, isolated hailstorm activities are also going on in some southwest districts.
These rainfall activities has been unusual because while not Rajasthan does receive some rains due to the Western disturbance and its induced cyclonic circulation, rainfall activity over southern parts of Rajasthan is only seen when a system appears in the Arabian Sea. However, this time, the induced cyclonic circulation along with moisture field from the Arabian Sea resulted in good rainfall activities over South Rajasthan.
Now, in the past 21 hours, rainfall activities have witnessed a reduction with Jaisalmer recording 11 mm of rain and Bikaner 3 mm. Other districts of the western parts of Rajasthan have observed light rainfall activities only.
The Western disturbance in the Himalayan region is moving away along with which its induced cyclonic circulation which was persisting over Western Rajasthan is also fading away. Due to this, there is expected to be a significant reduction in rainfall activities.
However, isolated rainfall may continue over northwestern parts of Rajasthan including Sri Ganganagar, Bikaner, Hanumangarh and Churu. Thereafter, the weather is expected to clear up.
Temperatures, particularly the minimums, are on a decrease at present, as North northwesterly cold winds from Jammu and Kashmir and Ladakh have been blowing over the region. These temperatures are expected to see a reduction further by around 3 to 4 degrees Celsius in the next 2 to 3 days.
Isolated pockets of Rajasthan, particularly the northern areas may observe temperatures dropping below 10 degrees including Sri Ganganagar, Bikaner, Hanumangarh and Churu, resulting in winter gripping these regions.
Thus, it is safe to say that after these rains completely cease, winter will commence over parts of Rajasthan and maintain its grip for some time.
