Many inland parts of NSW are facing their driest April in more than a decade, with some towns having seen no rain at all this month. A series of broad, slow-moving high pressure systems have been responsible for predominantly clear skies and dry conditions, while preventing any strong rain-bearing fronts from reaching inland areas. With only one day to go, much of the Upper Western is set to end the month with zero rainfall. This includes Brewarrina, Cobar and Lightning Ridge. It has been five years since Brewarrina and Lightning Ridge saw a dry April, and at least ten years for Cobar. Gunnedah and Narrabri Airport, on the Northwest Slopes and Plains, have also completely missed out on rain for the first time in at least a decade. Meanwhile, less than a millimetre has landed in the gauge at Walgett, making it the driest April in at least 18 years. The area of dry extends south to the Central West Slopes and Plains, where Forbes and Dunedoo are facing their first dry April since 2005 and Coonabarrabran since at least 2003. The state's parched south will have to wait another day to see how their monthly totals stack up, as a low pressure trough brings patchy rain and showers. Deniliquin had a light shower on Monday morning, bringing their monthly total to two millimetres. If less than 6mm more falls, they won't have seen a drier April in nine years. Similarly, Albury Airport's monthly total reached just under 11mm after lunch today. A total of below 20mm will make it the driest April since 2005. Looking ahead, another trough may bring further showers to far southern parts of NSW on Wednesday. Northern inland areas will have to wait at least another week for a drink, with indications that another trough will bring light showers early next week.
